What happens when you pull the plates of a capacitor apart?

As you pull apart the capacitor plates you are increasing the amount of space in which the E field is non-zero and hence increase the stored energy.

What happen if plate of a charged parallel plate capacitor are pulled apart?

If the plates are pulled apart. No chage will not change , because after disconnecting from battery charge remains constant.

What happens when plate separation is doubled?

A capacitor has fixed charges on its plates as the separation between the plates is doubled. The energy stored in the capacitor is proportional to the charge squared divided by the capacitance, but the capacitance will be cut in half if the plate separation is doubled. Therefore, the energy stored will double.

What happens to energy stored in capacitor if the plates of charged capacitor are drawn apart the battery remaining connected?

The plates of the capacitor is still connected to the battery, hence moving the plates further apart decreases the capacitance, hence energy stored in the capacitor decreases.

When plates of a charged capacitor are more separated while the capacitor is still connected to a charging battery?

If the capacitor remains connected to the battery V remains constant. Doubling the plate separation halves the capacitance so the stored energy reduces to 1/4.

What happens to the charge on the capacitor plates?

The charge remains the same. The capacitance goes down. So as capacitance goes down, voltage goes up. The energy for this comes from the effort expended in moving the charges apart.

Would the charge change if the plates were pulled without battery?

With no battery connected to the plates the charge on them has no possibility of changing.

How is the capacitance of a parallel plate capacitor affected by the charge on the plates?

Capacitance is directly proportional to the electrostatic force field between the plates. Therefore, as the distance between the plates decreases, capacitance increases.

What will happen if the charge on a parallel plate capacitor is doubled?

If the charge on a parallel-plate capacitor is doubled: A. the capacitance is halved. the surface charge density is not changed on either plate.

When the potential difference between the plates of a capacitor is doubled?

If the potential difference across a capacitor is doubled, the energy stored in it is quadrupled.

When the plates of a charged capacitor are brought closer what happens to the capacitance and energy stored?

Pressing the key pushes two capacitor plates closer together, increasing their capacitance. A larger capacitor can hold more charge, so a momentary current carries charge from the battery (or power supply) to the capacitor. This current is sensed, and the keystroke is then recorded.

What happens if the distance between two plates of a capacitor is increased while connected to a battery?

On increasing the distance between the plates, the electric field inside the capacitor connected to a battery weakens as distance is inversely proportional to the electric field inside the capacitor.
