Question

Example 1: If an electric heater consumes electricity at the rate of 500W and the potential difference between the two terminals of electric circuit is 250V, calculate the electric current and resistance through the circuit.​

Answer 1

Answer:

the electric current and resistance through the circuit is 5

Explanation:

Answer 2

Answer: Now by power formulae,

, P=V×I

500W=250V×I

Then, I=500/250

I=2A

Now by ohms law R=V/I

R=250/2 =125ohms.
