For example if a variable resistor has 100 between ends x and y The total length of the element is 10 m If the wiper is placed at a position on the element where the distance between the point y and the wiper is 4 m Then calculate the effective resistance Here R 1 100 l 10 m l1 4 m Variable resistors are resistors that change resistance from zero to a certain maximum value They are commonly used as volume controls and voltage regulators Variable resistors can be categorized into three types Potentiometers Rheostats Digital potentiometers Symbols for Variable Resistors Potentiometer
V IR What is a Variable Resistor A variable resistor possesses an adjustable electrical resistance value making it a crucial component in electronic circuits for adjusting current or voltage according to Ohm s Law A simple example would be the speed control of single phase induction motor ceiling fan through a potentiometer variable resistor Variable Resistor Definition Its an element which offers variation in load current or voltage due to change in its internal resistance
