Question

rheostat and variable resistance difference​

Answer 1

Answer:

hy your answer

Explanation:

A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. The construction is very similar to the construction of a potentiometers. It uses only two connections, even when 3 terminals (as in a potentiometer) are present.

Answer 2

A rheostat is a variable resistor used to control current by varing the resistance . It can be used to control downstream devices like transistors,dimmer switches etc. Variable resistor is an electrical component used to vary the amount of current that flows through the circuit.
