How is Voltage divided in a series circuit?

The supply voltage is shared between components in a series circuit.
The sum of the voltages across components in series is equal to the voltage of the supply.
The voltages across each of the components in series is in the same proportion as their resistances. This means that if two identical components are connected in series, the supply voltage divides equally across them.
