562·Chapter 18 Electrical Phenomena: Forces, Charges, Currents discha 18-33. When a battery is connected through a small bulb to a capacitor, the fact that the bulb dims and goes out after a charge brief interval is evidence that the capacitor plates do not keep athe gaining charge indefinitely. Use what you know about elec- trostatic forces on electrons to explain why a. the negative b. the plate of the capacitor doesn't keep getting more negative indef initely. b. the positive plate of the capacitor doesn't keep get- c. the cap cap ting more positive indefinitely can

Explanation / Answer

When a battery is connected through a small bulb to a capacitor, initially electrons start getting deposited on capacitor plate at a faster rate. later on the new coming electrons are repelled by existing electrons on the plates. so the rate of deposit of electron keep on decreasing and it becomes infinitely small rate. Hence the bright bulb initially becomes dim and then goes out.

The exact reverse thing happens on positive plate of the capacitor.
