the capacitance of an object is the amount of charge it is able to store per unit of potential difference across it.
C=Q/V
C in farads, f Q in coulombs, C V in volts, V
Capacitor: an electrical component that can store charge, made up of two conducting plates seperated by a dielectric.
- when a capacitor is connected to D.C., charge builds up on its plates.
- one plate becomes +ve and one becomes -ve
- plates are seperated by electrical insulation so no charge moves between them.
-this means a potential difference builds up between the plates.
