Series and Parallel circuits - Current, Voltage and Resistance

A short work consolidating ideas about current, voltage and resistance in series and parallel circuits.
Students should ideally know the ‘rules’ for current and voltage in series and parallel circuits:

1. voltage is shared across components in series.
2. Current is the same at each point in the circuit in series.
3. Voltage across components in parallel is the same as the supply
4. The total current in a parallel circuit is the sum of the currents in each ‘loop’.
