When plates of a charged capacitor are more separated?

The separation between the plates of a charged capacitor is to be increased. Explain when work done will be more in case battery is removed after charging the capacitor or battery remains connected. When, seperation between the plates of a charged capacitor increases, capacitance 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 when you separate capacitor plates?

The correct answer is that the charge remains constant. The capacitance decreases as the plates are separated, and the voltage increases in inverse proportion. I.e., if you halve the capacitance, the voltage doubles. Since the energy stored is proportional to capacitance and to voltage squared, the energy is increased!

What happens to a parallel plate capacitor when you push the plates closer together?

Larger plates provide greater capacity to store electric charge. Capacitance is directly proportional to the electrostatic force field between the plates. This field is stronger when the plates are closer together. Therefore, as the distance between the plates decreases, capacitance increases.

When a charged capacitor is disconnected from the battery and if its plates are separated further then find the change in its potential energy?

Now, if its plate are separated further, the potential energy will fall. Reason : Energy stored in a capacitor is equal to the work done in charging it.

What will be the effect on potential difference when separation between plates of capacitor increases?

The potential difference across the plates is Ed, so, as you increase the plate separation, so the potential difference across the plates in increased. The capacitance decreases from ϵA/d1 to ϵA/d2 and the energy stored in the capacitor increases from Ad1σ22ϵ to Ad2σ22ϵ.

What happens to the energy stored in the capacitor if the plates of a 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.

What happens to the energy stored in a capacitor if the plates of a charged capacitor are moved farther the battery remaining connected?

If the plates of a charged capacitor are moved farther after the battery is disconnected, the energy stored increases by the amount of work done by the external agent in pulling the plates apart against the force of attraction between the opposite charges on the plates.

When the plates of a charged parallel plate capacitor are pulled apart keeping charge constant?

What would happen if you pulled two charged capacitor plates apart? The charge remains the same. The capacitance goes down. So as capacitance goes down, voltage goes up.

What happens to potential difference if plates of a charged parallel plate capacitor are pulled 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.

Why the capacitor voltage decreases as the plates get closer?

As the plates move closer, the fields of the plates start to coincide and cancel out, and you also travel through a shorter distance of the field, meaning the potential difference is less, therefore capacitance increases C=Q/V, because the charge on the plates is fixed, you are just moving the plates.

How does a parallel plate capacitor work?

A parallel plate capacitor can only store a finite amount of energy before dielectric breakdown occurs. It can be defined as: When two parallel plates are connected across a battery, the plates are charged and an electric field is established between them, and this setup is known as the parallel plate capacitor. Parallel Plate Capacitor Formula

What happens when a capacitor is connected in series with a battery?

If a capacitor is connected in series with a battery, then the potential difference between the plates is fixed and equal to the voltage of the battery. Therefore, if the capacitance changes, then the charge on the capacitor plates must change as well in order to keep the potential difference between the plates constant.

What happens if the plates of a capacitor have unequal charge?

If the plates of a capacitor have unequal charge, there is now energy stored in more than one capacitance. There is the capacitance that exists between the two plates (the mutual capacitance) as well as the capacitance of each plate to the environment.

What happens to the energy lost when a capacitor is removed?

The energy lost by the capacitor is given to the battery (in effect, it goes to re-charging the battery). Likewise, the work done in pulling the plates apart is also given to the battery.
