Detailed Solution

The heating effect of electric current is the phenomenon where electric energy is converted into heat energy when current flows through a conductor.

When an electric current passes through a wire, the resistance of the wire opposes the flow. This resistance converts some electrical energy into heat energy. The amount of heat produced depends on current, resistance, and time.

Formula

The heat generated is given by H = I²RT, where:

I = current in amperes
R = resistance in ohms
T = time in seconds

Applications

Device	Use of Heating Effect
Electric heater	Heating rooms and water
Electric bulb	Filament glows due to heating
Electric iron	Pressing clothes
Fuse	Melts when current is too high, protecting circuits
