Two identical incandescent light bulbs are connected as shown in figure. When the circuit is an AC voltage source of frequency f, which of the following observations will be correct.

A

Both bulbs will glow alternatively

B

Both bulbs will glow with same brightness provided `f = (1)/(2pi) sqrt((1 // LC))`

C

Bulb `b_(1)` will light up initially and goes off, bulb `b_(2)` will be ON constantly

D

Bulb `b_(1)` will blink and bulb `b_(2)` will be ON constantly

Text Solution

Verified by Experts

The correct Answer is:
A

At t = 0, capacitor will be short circuit and inductor willbe open circuit.
After some time capacitor will be open circuit and inductor will be short circuit and so on
