Question

If an electric heater consumes electricity at the rate of 500W and the potwntial difference between the two terminals of electric circuit is250V calculate the electric current and resistance through the circuit

Answer 1

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.
