Joule's heat of electricity:
H= I^2.R.T = V^2 /R.t (OPTION A)
Explanation:
The heat of electrical current is given by the Joule's law of electrical heating.
In every current carrying conductor there is a resistance by the non-conducting particles of the material. This offers a continuous resistance to the charge carriers in the conductor and due to the collision the temperature of the conductor rises.
The heat thus produced is directly proportional to the time for which the current flows.
