A $$60 \ Watt$$ bulb operates on $$220 \ V$$ supply. The current flowing through the bulb is
Correct option is B. $$\dfrac{3}{11} \ amp$$
The power rated on the bulb $$P = 60 \ W$$ ,it operates on $$V = 220 \ V$$ supply .
Power is given by $$P=Vi$$
Hence,$$\Rightarrow i = \dfrac{P}{V} = \dfrac{60}{220} = \dfrac{3}{11} \ amp $$
