Question

Derive an expression for the heat produced in a conductor on passing electric current.​

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.

Answer 2

Answer:

W = V x I x t.

And the work done is dissipated as heat.

Therefore, Heat produced, H=W=V x I x t => VIt.
