Please explain all calculations.

The figure below shows a circuit consisting of a battery, a switch, two identical lightbulbs, and a capacitor that is initially uncharged. Immediately after the switch is closed, are either or both bulbs glowing? Explain. If both bulbs are glowing, which is brighter? Or are they equally bright? Explain. For any bulb (A or B or both) that lights up immediately after the switch is closed, does its brightness increase with time, decrease with time, or remain unchanged? Explain.

Explanation / Answer

initially capacitor is uncharged

only load in the circuit are blubs

a)

current flows thrgouht them.

so bulbs are glowing

b)

they are identical and ocnnected in series.

same current flows throguh them

both of them will have same brightness

c)

over time capacitor gets charged

so current in the circuit decreases.

so birghtness decreases
