Question

In the circuit below the light bulbs are identical and the battery is ideal. Initially, the capacitor is uncharged.

QUESTION 1: Pick the correct answer of the five options

A: Bulb A is initially unlit and then increases in brightness to a steady level.

B: Bulb A is initially unlit and remains unlit.

C: Bulb A is initially lit and then decreases in brightness but does not go out.

D: Bulb A is initially lit and then decreases in brightness until it goes out.

E: Bulb A is always lit and its brightness stays the same.

QUESTION 2: pick the correct answer out of the five options.

A: Bulb B is initially unlit and then increases in brightness to a steady level.

B: Bulb B is initially unlit and remains unlit.

C: Bulb B is initially lit and then decreases in brightness but does not go out.

D: Bulb B is initially lit and then decreases in brightness until it goes out.

E: Bulb B is always lit and its brightness stays the same.

QUESTION 3: pick the correct answer of the five options

A: Bulb B is Brither than bulb A

B: Bulb B is dimmer than bulb A

C: both bulbs have the same brightness

D: there is not enough information

Initially after Switch is closed ,Capacitor acts as short Circuit .So Current will pass through Bulb B only ,

After some time Current passes through both bulbs .

A: Bulb A is initially unlit and then increases in brightness to a steady level

After long Time ,capcitor acts as Open Circuit ,so

C: Bulb B is initially lit and then decreases in brightness but does not go out.

After long time capacitor acts as open circuit ,since both bulbs are identical ,they have simillar brightness

C: both bulbs have the same brightness
