Question

Heat energy is being produced in a
resistance in a circuit at the rate of
100 W. The current of 3 A is flowing
in the circuit. What must be the
value of the resistance?(Ans: 1192)​

Answer 1

Answer:

Given that,

Power, P=100W

Current, I=3A

Power,

P=VI

P=I2R

R=I2P

So,

R=9100

R=11.1Ω

Answer 2

Answer:

resistance=power/square of current

resistace=100/9=11.11

this is the right answer
