Question

1. H = 2 X RX t is called as
mark)
2. Heat energy is being produced in a resistance in a circuit at the rate of 100
Watt. The current of 5A is flowing in the circuit. What is the value of resistance?
(2marks)​

Answer 1

Answer:

1) Heat produced ,H=i^2RT iss called Joules Heating Law.

2) Power= 100W

Current= 5A

Power= I^2R

R= Power

I^2

R= 100

5*5

R= 4

Therefore, resistance= 4ohm
