Heating effect of electric current class 12
WebPutting the values of q and V in equation (1), we get. W = (I X t) X (I X R) Or W = I 2 Rt. Now, assuming that all the work done is converted into heat energy we can replace symbol of ‘work done’ with that of ‘heat produced’. So, H = I 2 RT. Applications of Heating Effect of Current.
