An electric bulb is designed to consume ...

An electric bulb is designed to consume `55 W` when operated at 110 volts. It is connected to a `220 V, 50 Hz` line through a choke coil in series. What should be the inductance of the coil for which the bulb gets correct voltage?

Text Solution

Verified by Experts

The correct Answer is:
`(2.2sqrt3)/(pi)=1.2H=(7sqrt3)/(10)H`
