Answer:
Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I^2Rt. This equation is called the Joule's equation of electrical heating. b)The resistance of the filament used in the bulb. A 2.5 kW immersion heater is used to heat water.

Answer:
The conversion of electrical energy into heating energy is called heating effect of current.
when the electrical energy passes through high resistance wire,like nichrome wire, the resistance become hot and produces heat.
example:electric oven, electric heater
