Voltage across components in a parallel circuit
The voltage across components connected in parallel is the same as the supply voltage for each component.
Voltmeter circuit
For a circuit with three branches, we could write this as;
\({V_s} = {V_1} = {V_2} = {V_3} = ....\)
Question
Look at the parallel circuit below - what is the reading on the voltmeter at each location when the switch is closed?
Position 1: 0V, 3V or 6V
Position 2: 0V, 3V or 6V
Position 3: 0V, 3V or 6V
Position 1 = 6V
Position 2 = 6V
Position 3 = 6V
