Question

Can anyone explain me the heating effects of electric current. The topic is of class 10.

Answer 1

Heating Effect of Electric Current

When an electric current is passed through a conductor, the conductor becomes hot after some time and produces heat. This happens due to the conversion of some amount of electric energy, passing through the conductor, into heat energy. This effect of electric current is called heating effect of electric current.

The heating effect of electric current depends on three factors:

The resistance, R of the conductor. A higher resistance produces more heat

The time, t for which current flows. The longer the time the larger the amount of heat produced

The amount of current, I. the higher the current the larger the amount of heat generated

Heating effect of 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. It quantifies the heating effect of electric current

I hope this helps you...

Answer 2

Jule's law of heating or heating effect of current is heat produced as action of voltage, electricity and time . we know that chemical reaction take place to generate potential difference as result electron flow and due to resistance of conducting wire heat is produce


H=VIt
H=I²Rt
