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 .
