Question

A current of 5 ampere in a10 ohm resistor. calculate the rate of energy producing in the resistor​

Answer 1

Answer:

Heat dissipated in a resistance is given by H=i

2

×r×t

For option A H=5

2

×10×2×60=30000W

For option B H=4

2

×10×3×60=28800W

For option C H=3

2

×10×6×60=32400W

For option D H=2

2

×10×5×60=12000W

from calculation we can see the heat Which is maximum in case of 3 ampere current for 6 minutes.
