What Is a Rheostat?

A Rheostat is a variable resistor used to regulate the flow of electric current in an electrical circuit. By moving the sliding contact along the resistance wire, the resistance changes, allowing users to control the current without altering the voltage source.

The 8-inch rheostat provides a longer resistance path, making it suitable for experiments requiring a wider range of resistance adjustment.

Working Principle

The Rheostat works according to Ohm’s Law.

When the sliding contact moves across the resistance wire:

• The effective length of the resistance wire changes.
• The electrical resistance increases or decreases.
• The amount of current flowing through the circuit is adjusted accordingly.

This allows students to study the relationship between voltage, current, and resistance through practical experimentation.
