1 Answer

Answer :

Resistor: a fixed resistance connected permanently in the circuit for limiting the current to definite value is called the resistor.

Rheostat: a variable resistance by sliding contacts on it the current can be varied is called rheostat.

Potential divider: when a resistance is used to develop a voltage drop it is called a potential divider.
