1. There are two types of circuits: series and parallel.
2. Series circuits have every component connected end to end on one wire.
3. In a series circuit, current is the the same over all components, but the voltage drops with each component according to Ohm's Law.
4. In a series circuit, Rt = R1 + R2 + R3...
5. In a parallel circuit, components are connected to separate wires that run next to each other.
6. In a parallel circuit, each branch has a separate current.
7. In a parallel circuit, Rt = 1 / ((1 / R1) + (1 / R2) + (1 / R3) ...)
