Question

Does the capacitance of a device depend on the applied voltage? What about the charge stored in it?

Answer 1

No and yes, respectively. The capacitance is an intrinsic property of the device. On the other hand, the stored charge is proportional to the voltage applied \( \left( Q = C\cdot V\right) \).

Answer 2

Can you quickly explain capacitance?

Answer 3

It's defined through the charge equation Q = CV. One way to think about it is that in SI units, a capacitor with a 2 Farad capacitance will store 2 Coulombs of charge for every volt applied across the device.

Answer 4

Okay Thanks so much!! I get it now

Answer 5

No problem.
