Difference Between Resistor, Rheostat and Potential Divider

Resistor

A fixed resistance connected permanently in the circuit for limiting the current to a definite value is known as a resistor. It should be capable of withstanding the temperature developed in it.

Rheostat

A variable resistance by sliding contact on it is called a rheostat. The current flowing through the circuit is controlled by inserting and varying the with the help of sliding contact.

Potential Divider

When a resistance is used to develop a voltage drop, it is called a potential divider.
