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?

A 60 W , 120 V bulb is connected to a 240 V , 60 Hz supply with an inductance in series. Find the value of inductance so that bulb gets correct voltage.

An electric bulb is designed to operate at 12 volts DC . If this bulb is connected to an AC source and gives normal brightness, what would be the peak voltage of the source?

An electric bulb has a rated power of 50 W at 100 V . If it is used on AC source of 200 V , 50 Hz , a choke has to be used in series with it. This choke should have an inductance of

An electric bulb is rated 220 volt - 100 watt. The power consumed by it when operated on 110 volt will be

An electric lamp which runs at 100 V DC and consumes 10 A current is connected to AC mains at 150 V, 50 Hz cycles with a choke coil in series. Calculate the inductance and drop of voltage across the choke. Neglect the resistance of choke.

An electric bulb is rated 200 V and 100 W. When it is operated on 110V, the power consumed will be:

An electric bulb is rated 220 V and 100 W . When it is operated on 110 V , the power consumed will be :
