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 % .
