Question

derive an experienced for the produced by electric current?​

Answer 1

Answer:

(a) When an electric charge Q moves against a p.d. V, the amount of work done is given by

W=Q×V                           ---------------(1) 

We know,  current , I=tQ

Q=I×t                                ------------(2)

By ohm's law , IV=R

V=I×R                             --------------(3)

Putting eqs. (2) and (3) in eq. (1),

W=I×t×I×R

W=I2Rt

Assuming that all the electrical work done is converted into heat energy , we get

Heat produced , H=I2Rtjoules

This relation is known as Joule's law of heating.
