6 FAQs about [Capacitors have a large distance]

Do capacitors have 'infinitely large' plates?

Obviously real capacitors don't have "infinitely large" plates. What should be said is that any dimension of the plates should be much greater than the distance between the plates (thickness of the dielectric, d) so that the electric field E can be considered constant between the plates (neglecting edge effects) and is E = V D.

What is a capacitance of a capacitor?

The voltage between the plates and the charge held by the plates are related by a term known as the capacitance of the capacitor. Capacitance is defined as: The larger the potential across the capacitor, the larger the magnitude of the charge held by the plates.

Why do capacitors have different physical characteristics?

Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage across their plates. The capacitance of a capacitor is defined as the ratio of the maximum charge that can be stored in a capacitor to the applied voltage across its plates.

How does distance affect a capacitor?

As Capacitance C = q/V, C varies with q if V remains the same (connected to a fixed potential elec source). So, with decreased distance q increases, and so C increases. Remember, that for any parallel plate capacitor V is not affected by distance, because: V = W/q (work done per unit charge in bringing it from on plate to the other) and W = F x d

How does the magnitude of the electrical field affect a capacitor?

The magnitude of the electrical field in the space between the plates is in direct proportion to the amount of charge on the capacitor. Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates.

What happens if a capacitor is charged to a certain voltage?

If the capacitor is charged to a certain voltage the two plates hold charge carriers of opposite charge. Opposite charges attract each other, creating an electric field, and the attraction is stronger the closer they are. If the distance becomes too large the charges don't feel each other's presence anymore; the electric field is too weak.
