6 FAQs about [Charging of two capacitors]

Why do all capacitors have the same charge?

Charge on this equivalent capacitor is the same as the charge on any capacitor in a series combination: That is, all capacitors of a series combination have the same charge. This occurs due to the conservation of charge in the circuit.

Do capacitor plates have a total charge?

As the capacitor plates have equal amounts of charge of the opposite sign, the total charge is actually zero. However, because the charges are separated they have energy and can do work when they are brought together. One farad is a very large value of capacitance.

How does a capacitor charge a battery?

When a capacitor charges, electrons flow onto one plate and move off the other plate. This process will be continued until the potential difference across the capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear.

How much charge is stored when a capacitor is charged?

When a capacitor is charged, the amount of charge stored depends on: its capacitance: i.e. the greater the capacitance, the more charge is stored at a given voltage. KEY POINT - The capacitance of a capacitor, C, is defined as:

What factors affect the rate of charge on a capacitor?

The other factor which affects the rate of charge is the capacitance of the capacitor. A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%).

How do you find the charge of a capacitor?

KEY POINT - The charge, Q, on a capacitor of capacitance C, remaining time t after starting to discharge is given by the expression Q = Q0e–t /τ where Q0 is the initial charge on the capacitor. Here e is the exponential function, the inverse of natural log, ln.
