Hi,
Does voltage drop across a capacitor and if so why does it? Also would a voltage drop only occur during discharge of a capacitor?

Thanks

Hi Sukham,

You want to remember the equation for quantifying charge on a capacitor: Q = CV. If you have a capacitor of a given Capacitance (C), then C is a constant. Therefore, Q is directly proportional to V.

As a capacitor discharges and the electrons are free to complete the circuit, the Q drops. As a result V drops as well. Therefore a voltage drop occurs during discharge.

Here's a link that may help you understand the fundamentals: https://www.khanacademy....rs/a/capacitors-article


hope this helps!
