Question

What is heating effect of current? Obtain an expression for the heat developed in a resistor by passage of an electric current through it. Hence state Joule’s law of heating.​

Answer 1

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 = I2Rt. This equation is called the Joule's equation of electrical heating.
