# Voltage across components in a series circuit

• The supply voltage is shared between components in a series circuit.
• The sum of the 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 . This means that if two identical components are connected in series, the supply voltage divides equally across them.
Question

Look at the series circuit below - what are the readings at each position when the switch is closed:

1) Position 1: $$0 V$$, $$3 V$$ or $$6 V$$

2) Position 2: $$0 V$$, $$3 V$$ or $$6 V$$

3) Position 3: $$0 V$$, $$3 V$$ or $$6 V$$

Position 1 = $$6 V$$

Position 2 = $$3 V$$

Position 3 = $$3 V$$
