Q. 114.3( 20 Votes )

100 joules of hea

Class 10th Lakhmir Singh & Manjit Kaur - Physics 1. Electricity

Answer :

Here, it is given H = 100J, t = 1sec, R = 4ohms,

We know that according to Joule's law of heating

H = I²RT

100 = I²×4×1

100/4 = I²

I = 5amp

Again we know that

V = IR

V = 5X4

= 20V
