Physics 201- Introduction to Electricity & Magnetism
|October 4- Capacitors|
A battery maintains a potential difference across its terminals.
The symbol for a battery:
Let's connect two large plates to the terminals
of a battery via a pair of wires. What happens? How much charge
is on each plate?
What happens if we move the plates?
Does the charge per plate change?
We need a quantity that describes how the
system will charge. The quantity that describes the system's
ability to hold charge is its capacitance. We will see that a capacitor
stores energy (you can convert this stored electrical energy to other forms).
