Question

Prove that the heat produced in a conductor of resistance R on passing current through it for time t is h=i^2rt

Answer 1

Answer:

H=I²RT

Explanation:

Consider a current I flowing through a resistor of resistance R. Let the potential difference across it be V. Let t be the time during which a charge Q flows across. The work done in moving the charge through the potential difference is VQ.

P=V×Q/T

=VI

Energy =power ×time

=VIT

H =VIT

V = IR

H = I²RT
