How to Calculate Resistor 4-5 colors
How to Calculate Resistors are things that need to be known by us when we are engaged in the engineering world . Resistor is one of the electronic components that one of its functions is to inhibit the flow of electricity . Wherein the resistor itself is passive component does not require electricity to work . In addition to inhibit the flow of electricity , also serves to lowering resistor and voltage divider , and also as a barrier or an electric current regulator . Resistor itself denoted by R has units of ohms . Resistor itself can be calculated to determine the value of the resistor itself.
To determine the value of the resistor we can see the color of the bracelet contained in the resistor body . There are several types of resistors based on the number of rings contained in the resistor body . Most of the resistors used is a resistor 4 to 5 bracelets .
How to calculate resistor four to five rings counted easily . For resistor 4 bracelets, bangles first and second digit is a number , a multiplier third bracelet , while the bracelet fourth is tolerance . For a resistor with 5 rings , bracelets first second and third digit numbers . The fourth bracelet contains a multiplier value . And tolerance values contained in the fifth bracelet . On the other resistor with six bracelets , digit numeric values contained in the first to third bracelet . For its multiplier value contained in the bracelet to four . Medium fifth bracelet containing the values of tolerance , followed by six to bracelets containing temperature coefficient .
As an example of how to calculate the resistor with the four rings in the order red bracelet , black , red , and gold is as follows . Position red bracelet on the first sequence containing 2 -digit numbers , black 0 , red for the third order worth multiplier 102 , and gold has a value of 5% tolerance. The resistor values of resistors four rings is 20 X 102 = 2000 Ω = 2 KΩ ± 5 % . Moderate to resistor five bracelet with orange order with a value of 3 , Brown 1 , Black 0 , 102 red , silver 10 % have a resistor value of 310 X 102 = 31000 Ω = 31 KΩ ± 10 % .

Resistor Symbol and Function
Resistor symbol is an icon of a resistor . Resistor itself is actually a passive electronic component . It implies that the resistor does not need electricity when working . Resistor itself serves to hold electric current by utilizing the two poles to produce electric voltage . Resistor itself has some symbols that serve to determine the value of the resistor to support components to be used . Of the various existing symbol we can determine the function of the resistor itself. To determine the value of the resistor itself, we can count on the color of the bracelet found on the body of the resistor . The calculation of the value of the bracelet color applied to the resistor type Film Film Carbon and Metal . Moreover , we can calculate the value of a resistor based on the figures contained in the type resistor SMD (Surface - mount device ) .
There are several symbols resistor now. The first is a symbol Fixed Value Resistors ( IEC Symbol) . This symbol has two straight poles with a rectangular box in the middle. For Fixed Value Resistors with zigzag line center. For Variable Resistor ( potentiometer ) has a line drawing arrows pointing zig- zag pattern in the middle. In the Variable Resistor ( Rheostat ) with images similar to the Variable Resistor yet crossed arrows image amid a zig - zag pattern . Additionally teradapat LDR or Light Dependant Resistors by drawing a circle in the center with a rectangle in the midst of the circle. The next symbol is Thermistor . Thermistor has a zig zag pattern display amid wrapped in a circle with the word " to " .
Resisitor symbols are intended to help us when knowing the type of resistor without looking directly form the desired resistor . Resistor itself has several functions in electronics rangakaian . The first, as we mentioned above resistor serves to hold electric current . Additionally resistor serves to constrain the flow of electricity . Various resistor also serves to divide the electric current and overcurrent safety on some components. Resistors also serves to lower voltage rated too high can result in damage to electronic components .

Types of Resistors at the moment there are only 2 types: Fixed Resistors ( Variable Resistor ) and Variable Resistor ( Variable Resistor ) . Of the two types of resistor are divided into several sections , the following we will describe the parts of both types are :
Fixed Resistors
Fixed Resistors ( Variable Resistor ) is a type of resistor whose value has been written on the resistor body by using color codes or numbers. This resistor is used as a barrier to electrical current permanently. The function of this resistor is as limiting the current flowing in the LED light . Types of fixed resistor is :
resistor Wire
Resistor Wire is a new type of resistor that was first used when the electronic circuit is still using vacuum tubes . The physical form of the resistor is varied and has a fairly large size . Because it has a high resistance and high resistance to heat , these resistors are only used in the power circuit . Until now , the kind that are still in use is the kind that has a coil wire in ceramic materials , then coated with cement .
Resistor Rod Carbon ( Charcoal )
This resistor is made of carbon materials rough and put their windings and the color-coded pins annular . To be able to read the resistance value of each color of the bracelet can use a color code table . This type of resistor is formed after the resistor wire . Currently, there are very few people who use carbon rod resistors in electronic circuits .
resistor Ceramics
With rapid technological advances , especially in the field of electronics . At this time has created the type of resistor made from ceramic or porcelain base material and coated with a thin glass . Because it has a small physical shape and also a high resistance value , the resistor is the most widely used in electronic circuits . Owned power rating of 1/4 watt ceramic resistor , 1/2 Watt , 1 Watt and 2 Watt .
Carbon Film Resistors
This resistor is the result of the development of the carbon rod resistors . In line with perkemangan technology , has formed resistor are made of carbon and is coated with a film material that serves as a protective barrier against external influences . The resistance value is already listed in tabular form a color code . Because it has a high resistance value and small physical form , this resistor is also widely used in various electronic circuits . Owned resistor power rating is 1/4 Watt , 1/2 Watt , 1 Watt and 2 Watt .
Metal Film Resistors
The shape of the metal film resistor is almost equal to the carbon film resistors . Only resistor is resistant to temperature changes and have a high level of accuracy because the value of tolerance which reached 1 % or 5 % . When compared with other types of fixed resistors , resistor has a higher precision due to choose a bracelet 5 colors and even some that are 6 bracelets colors. Metal film resistors are widely used in electronic circuit that has a high level of accuracy , such as measuring instruments.
Variable Resistor
Variable Resistor : is a type of resistor has a resistance value directly changeable by rotating the shift lever existing atupun . Type of Variable Resistor are :
potentiometer
Potentiometer is a type of variable resistor whose resistance value can we change by turning around its axis via a lever that has been provided . In general , these resistors are made of wire or carbon and most widely used in the circuit elektornika . When this has been a lot of potentiometer made of carbon material because it has a smaller size and resistance are quite large. Changes in the value of the resistance is divided into two , namely linear and lpgarithmic . To determine whether the linear potentiometer or lpgarithmic can be seen from the letters that are printed on the back . When shown the letter " B ", then the potentiometer is lpgarithmic , whereas if the printed letter " A " then the linear potentiometer .
trimpot
Trimpot or commonly called Tripotensiometer is a resistor whose resistance value can be changed . The nature and characteristics of the trimpot not much different from a potentiometer , only the physical form trimpot smaller than with a potentiometer . The resistance value changes are also divided into two , namely linear and lpgarithmic . To change the resistance value by turning the trimpot hole in the body by using a screwdriver .
NTC and PTC
NTC (Negative Temperature Coefficient ) and PTC ( Positive Temperature Coefficient ) is a resistor whose resistance value can be changed if there is a change in the surrounding temperature . NTC resistance value itself will go up if the temperature around him down , while the resistance value of the PTC will rise if the if the temperature around them rises . Both resiston is most commonly used as a sensor because it can measure the temperature or the temperature of the surrounding area .
LDR
LDR ( Light Dependent Resistor ) is a resistor whose resistance value can be changed in the event of changes in light intensity in the surrounding area . That can happen because of the intensity of light that can induce electrons to penetrate the boundaries of the LDR . Thus , the resistance value will increase the intensity of the received bit jiga . Sedangkana resistance value of the LDR would drop if the intensity of light received lots . Resistor LDR itself is widely used as a light sensor , especially on a garden light .Sabtu, 25 Juni 2016

Resistor complete understanding
Resistors are electronic components that are designed to have two poles that can be used to stem the flow of electricity when the power supply voltage aliri between the two poles . The resistors are commonly used as part of an electronic circuit . Not only that , the resistor is one of the components is also the most commonly used among other components . , Resistor is a component made of insulating material containing a certain value in accordance with the desired resistance value . Based on Ohm's law , resistance is proportional to the value of the voltage ampere current flowing.
The shape of the resistor itself today is diverse . The most common and often found on the market is elliptical and there are several circles of color on the body of the resistor . There are 4 circles that exist in the body of the resistor . The color circle is used to show the value of the resistance of the resistor . see also : the resistor color code
Resistor function very big influence in the electronic circuit , because it can be used as a drag stream flow while before it is processed and distributed to other electronic components . Aside from being a barrier as the current , resistor divider can also function as a current limiter / current divider , lowering the voltage and the voltage divider . Resistors are also a component that inhibits electrical current passive manifold .
Types of Resistors are now widely sold in the market , here we explain in detail the types of resistors :
Resistor Variable ( Value Change - Change )
Resistor that one is very different from an ordinary resistor , in which the value of a variable resistor can be changed by rotating or sliding components.

The main characteristics of the resistor is the resistance and electric power can be delivered . Meanwhile , another characteristic is the temperature coefficient , electrical noise (noise ) and inductance . Resistors also can be integrated into hybrid circuits and circuit boards , and even can also use integrated circuits . The size and location of the foot resistor depends on the design of the circuit itself , the resistor power generated must also comply with the requirement that the circuit does not burn .

So it made sense that all the electronic circuits that exist in this world always use the resistors . Resistor is also a component of the most famous , but because the price is cheap components is also the most widely sold in the market . So you do not need to be confused and dizzy to look for this one component .
Ordinary Resistor ( Fixed Value )
Resistor function as inhibitors of the motion of electric current whose value can not change ( constant ) . The materials used to manufacture these resistor is Nickel and Carbon .
