Question

What do you mean by heating effect of electric current?

Answer 1

HEATING EFFECT OF ELECTRIC CUURENT. When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: ... A higher resistance produces more heat.

Answer 2

When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors:

1. The resistance, R of the conductor.

A higher resistance produces more

heat.

2. The time, t for which current flows.

The longer the time the larger the

amount of heat produced

3. The amount of current, I. the higher

the current the larger the amount

of heat generated.

Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I²Rt. This equation is called the Joule’s equation of electrical heating.
