Question 16.
Solve the example.
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:
Answer: Given Power P = 100 W
Current I = 3 A
R =?
We know P = I2R;
where R is resistance
So R = P/ I2
⇒, R = 
= 11.11 ohm
