An electric bulb has a rated power of 50 W at 100 V. If it is used on an AC source 200 V, 50 Hz, a choke has to be used in series with it. The should have an inductance of
View answer and explanation
Correct option: D
1.1 H
Option D (1.1 H) is correct because the inductance is calculated based on the required impedance to limit the current through the bulb when used with a 200V source.

Assertion (A) : In an circuit, potential difference across the capacitor may be greater than the applied voltage.
Reason (R) : , whereas and can be greater than also. When power is drawn from the secondary coil of the transformer, the dynamic resistance An alternating e.m.f. is applied to purely capacitive circuit. The phase relation between e.m.f. and current flowing in the circuit is or
In a circuit containing capacitance only
Average power in the L-C-R circuit depends upon A generator produces a voltage that is given by , where t is in seconds. The frequency and r.m.s. voltage are In a choke coil, the resistance and resistance are such that
