Question

State the joule's law of heating Find the expression
for amount of heat produced​

Answer 1

Joule's law of heating states that , "The heat produced in a resistor is directly proportional to (1) square of current (I^2) (2) resistance of the resistor (R) and (3) time for which the current flows through the resistor .

H = V I t = I2Rt. this energy is dissipated as heat energy. This relationship is also known as Joule's Law of Heating.

Answer 2

Answer:

joules law of heating states that heat or energy produced is directly proportional to the square of current supplied, resistance of conductor and time.

H dp I²

H dp R

H dp t

H= I²Rt
