A Level Physics Revision: All of Capacitors (in under 21 minutes)

Capacitors in parallel and resistors in parallel share a similar principle where the total capacity (or total resistance) is derived from their individual contributions. However, the electrical characteristics behave differently.

For capacitors in parallel, the total capacitance increases with each additional capacitor, similar to how resistors in series add together to increase total resistance. Conversely, for resistors in parallel, the total resistance decreases as more resistors are added.

Additionally, in a capacitor circuit, the total charge available increases and the voltage across each capacitor remains the same. In contrast, when resistors are in parallel, the voltage across each resistor remains constant while the total current splits among them.
