Question

13.How much will be the heat developed if 2 A current flows through a conductor of resistance 200 Ω for 2 minutes?

1600 J

96000J

9600J

None of these​

Answer 1

I = 2A

R = 200Ω

t = 2min = 2*60 = 120s

H = I²Rt

H = 2²*200*120

H = 4*200*120

H = 96000J

Answer 2

Answer:

96000J

Explanation:

H=I^2*R*T

H=(2)^2*200*2*60

H=4*200*2*60

H=96000J
