Q
Compare a capacitor and a battery
A
2
Q
What is a capacitor?
A
A device designed to store energy by storing charge.
Energy is stored in electrostatic fields in the form of electrostatic potential energy. Two metal plates are separated by an insulator
3
Q
What does it mean to store a total charge of Q?
A
*electron flow is not the same as conventional current
4
Q
What is the capacitance C of a capacitor defined as?
A
Charge stored per unit p.d
5
Q
What is capacitance ?
A
A property of a capacitor, deep and on its design and construction. All capacitors do not behave the same way despite applied p.d
6
Q
What is the charge stored in a capacitor dependant on?
A
7
Q
What is the capacitance formula?
A
AS physics
