Capacitance

This lecture is based on HWR, Sections 26.1-26.3.

Capacitance is a measure of the ability to store charge given some potential difference. It is defined as
```
            Capacitance = charge / voltage
```
The unit of capacitance is the farad = (coulomb/volt)
A capacitor can store charge, or energy, for later use. It may also be used to filter out transient surges of current in a circuit
To calculate the capacitance of a device, just determine the charge on the device, and the voltage across it.
