Problem 7 (6.25 pts): The circuit below contains a battery, a bulb, a switch, and two identical capacitors. The capacitors initially uncharged. Predict the behavior of the bulb after the switch is closed: A) Because the bulb is not directly connected to the battery, it w not light up B) The bulb will not immediately turn on, but will slowly get brighter after a long while C) The bulb will turn on immediately, but will slowly grow dimmer after a long while D) The bulb will slowly flash on and off. E) The bulb will immediately turn on and stay on

Explanation / Answer

ANswer is C)The bulb will turn on immediately ,but will slowly grow dimmer after a long while

Immediately after switch is closed both capacitors will act as short circuit Then light will glow at t=0 ,after long time capacitors become fully charged and act as open circuit ,then the light at t=infinity will get dimmer
