- Components connected in series are all part of the same branch of a circuit.
- The current through each component will be the same.
- The potential difference will be split between components dependent on their resistances.
- The total potential difference across the components must be equal to that of the power supply: \(V_\text{supply}=V_1+V_2\).
- When connecting cells and batteries in series, the power supply is the sum of their potential differences as long as they are all directed the same way.
- The total resistance, in Ω of two components connected in series is given as \(V_\text{total}=R_1+R_2\). Connecting resistors in series will increase the total resistance and reduce the current through them.
