Question

2 A is passing through a conductor of resistance 200 Ω for 5 mts .Calculated the heat energy produced

Answer 1

Given:

Current I = 2A

Resistance R= 200 Ω

Time t = 5

The heat developed in any electric device for a given time is given by Joule's law of heating,

H = I² Rt

H=(2)²× 200 × 5 = 4000 J

So,the heat developed in the conductor is4000 J
