Resistor is the electronics component that functioned as the resists of electric current. The resistor unit was ohm (
), it was taken from the name of its discoverer that is George Ohm. Relations between the value of the resistor (resistance) and the electric current and voltage are :
V = IR. The electrical resistance R is equal to the voltage drop V across the resistor divided by the current I through the resistor. Resistors are used as part of electrical networks and electronic circuits.
