Question

what is rheostat...................

Answer 1

VARIABLE resistance is component used to regulate current without changing the source of the voltage is called rheostat.

Answer 2

Rheostat definition

Rheostat is a variable resistor, which is used to control the flow of electric current by manually increasing or decreasing the resistance. The English scientist Sir Charles Wheatstone coined the word rheostat, it is derived from the Greek word “rheos” and “-statis” which means a stream controlling device or a current controlling device.

What is rheostat?

The electric current flowing through an electrical circuit is determined by two factors: the amount of voltage applied and the total resistance of the electrical circuit. If we reduce the circuit resistance, the flow of electric current through the circuit will be increased. On the other hand, if we increase the circuit resistance, the flow of electric current through the circuit will be decreased
