RC Circuits and Statistics
The charge q on a capacitors plate is proportional to the potential difference V across the capacitor. We
express this with,
q
V
C
where C is a proportionality constant known as the capacitance. C is m

Series and Parallel Circuits
Components in an electrical circuit are in series when they are connected one after the other,
so that the same current flows through both of them. Components are in parallel when th
