Question
Which statement best describes the behavior of the lamp when the switch is closed (downward) and then opened (upward) again after a long while? When the switch is closed, the lamp hellip instantly turns on at full brightness, and then instantly turns off Slowly brightens to full brightness, and then slowly dims instantly turns on at full brightness but then slowly dims, and then repeats this behavior does not turn on, but then turns on at full brightness and slowly dims hellip when the switch is opened.Explanation / Answer
The correct statement is (C).
Immediately after the switch is closed, the current flow in the circuit is maximum.After a long time,the capacitor charges fully and current flow in the circuit becomes zero. The current flow in the circuit decreases with time after switch is closed.
The brightness of the bulb is directly proportional to the current flow.
