Question
Choose the graph of Brightness vs Time below that most accurately describes the time behavior of the brightness of the light bulb in the center branch of the circuit shown. Note that the lower-right branch (with a capacitor) has a resistor of value 2R, while the lower-left branch (with an inductor) has a resistor of value R. YOU MUST EXPLAIN YOUR CHOICE!

YOU MUST EXPLAIN YOUR CHOICE!Explanation / Answer
ANS -: a
explanation--
1. initialy there is no current. so brightness =0
2. Because this circuit has R,L,C components so it will oscillate at a particular frequency after steady state and this will ensure constant current.
