Question

A capacitor is connected to a power source and begins charging.

What causes the capacitor to stop charging while it is still connected to the power source?

The power source runs out of electrons to send to the charged plate.
No additional positive charges can be moved onto the second plate.
The charged plates attract each other and touch, causing a discharge.
Electrons are too strongly repelled from the negatively charged plate.

Answer 1

D.Electrons are too strongly repelled from the negatively charged plate.

Answer 2

Electrons are too strongly repelled from the negatively charged plate.

Step-by-step explanation:

A capacitor is a device that stores energy by holding apart pairs of opposite charges. The opposite charges are put in parallel plates. When it's charged by a power source, it's source is sending electrons to the capacitor, thus, it will be put in the negatively charged plate. At some point, the attractive force between the plates will be weaker than the repulsive forces of the electrons and the negatively charged plate, then, they'll be repelled and the capacitor will stop charging.
