Question

Two identical incandesant 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/ 2π) √(11LC)

(c) Bulb B₁ will light up initially and goes off, bulb B₂ will be  ON constantly.

(d) Bulb B₁ will blink and bulb B₂ will be ON constantly.

Answer 1
