Question

Solve the following example.

1) 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?​

Answer 1

Answer:

Given: H=100w, l=3A

To find =R = ?

Heat generated =100w

Power=100w

Power=V×l

100=V×3

V=33.3V

Now

By ohms law

V=lR

33.3=3×R

R=11.1

The value of resistance is 11

Explanation:

This is a case of ohm's law

hope it helps you my friend.
