1. The sum of the component voltage drops in a series circuit is equal to the voltage at the source.

Vs=V1+V2+...+Vn (s=source, n=total number of voltage drops in the circuit)

2. The greater the resistance imposed by a component, the greater the voltage drop across it.

Larger resistor=larger voltage drops, Smaller resistor=smaller voltage drops

3. In a series circuit, the percentage of resistance contributed by a component is equal to the percentage of voltage dropped by that component.
