Question

Solve the following example.

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

Answer 1

Answer:

11

Explanation:

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

Answer 2

Answer:

11.12 omega

Explanation:

by using the formula...

P = I^2R
