Exam Favourite
Examined in Edexcel 1PH0/2 (Paper 2). Circuit calculation questions are multi-step: series/parallel combinations with Kirchhoff's Laws context. Context-based: household appliance scenarios and fault-finding. "Suggest" questions for novel circuit behaviour. Series and parallel circuits appear in almost every GCSE Physics paper. Circuit calculations are worth 3–6 marks and test your ability to apply multiple rules in sequence.
What examiners love to ask:
- Identify whether a circuit is series, parallel, or mixed
- Calculate total resistance for series or parallel combinations
- State the current or voltage at a specific point
- Explain why houses are wired in parallel
- Solve multi-step mixed circuit problems (Higher tier)
- Explain why one broken component in a series circuit stops everything
This exam focus covers Exam Focus within Series & Parallel Circuits for GCSE Physics. Revise Series & Parallel Circuits in Electricity for GCSE Physics with 20 exam-style questions and 30 flashcards. This topic appears less often, but it can still be a useful differentiator on mixed-topic papers. It is section 14 of 16 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
Practice questions for Series & Parallel Circuits
In a series circuit, what is true about the current at all points?
A student adds an extra lamp to a parallel circuit. Explain how this affects the total current from the supply and the brightness of the original lamps.
