Question

Solve numerical?
If a bulb of a 60 W is connected across a source of a 220 V,find the current drawn by it ?​

Answer 1

Solution : Data : P=60 W, V=220 V, I=?

P=VI

∴ I=P/V=60W/220V=(3/11)A = 0.2727A

The current drawn by the bulb = 0.2727A (Approx)

Answer 2

Answer:

since p = IV

I = P/V

I = 60/ 220
