# A technician is wiring the lights in a new house. She must decide whether to connect the lights in series or in parallel. Explain why connecting the lights in parallel is more suitable than connecting them in series for use in a house.

> Eduqas GCSE Physics — 7.2 Series and parallel circuits · Explain · 4 marks

## Mark scheme (4 marks)

1. In a parallel circuit, each lamp has its own independent branch / switching off one lamp does not affect the others
2. In a series circuit, if one lamp breaks/is switched off the circuit is broken and all lamps go out
3. In a parallel circuit, each lamp receives the full supply voltage
4. In a series circuit, the voltage is shared/divided between the lamps so they would be dimmer
