RESISTOR

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. They can also be used to provide specific voltages to active components. Resistors are available with fixed or variable resistance values. Fixed resistors are ones in which resistance never changes whereas variable resistors, sometimes called potentiometers, allow resistance to be adjusted. Resistor values are measured in Ohms and a resistor’s composition and construction determines the amount of resistance offered. Typically, resistors are made of metal or carbon and are available in a variety of mounting styles, but through hole and surface mount are the most common.
