Question

State Joule's law of heating.

Answer 1

HEYA FRIEND,☺️

HERE IS YOUR ANSWER,
◆◆◆◆◆◆◆◆◆◆◆◆◆◆◆◆◆◆◆◆◆◆◆

When current I flow through a resistor of electric resistance R, heat is produced. The heat produced H depends directly on the square of the current, resistance and time t for which the current is allowed to pass. H=I2Rt, Is called Joule's law of heating.

Answer 2

HERE IS THE ANSWER;

◆ When a current of I (amperes) passes through a circuit of resistance R (ohms) for a time of t (seconds) then the heat produced is given by the relation is:

H=I2Rt    (joules)

【 Note: The unit of heat will be in Joules & There is the derivativation of its formula.】
