Examined in Edexcel 1PH0/2 (Paper 2). Edexcel separates "charge flow" and "current" carefully in mark scheme language — use the precise terms. Context-based questions use household appliance scenarios. Current and charge is one of the most frequently examined topics in GCSE Physics electricity. Expect it in every paper.
What examiners love to ask:
- Calculate charge given current and time (Q = It)
- Rearrange to find current (I = Q/t) or time (t = Q/I)
- Describe what an ammeter measures and how to connect it
- Explain the difference between conventional current and electron flow
- State the unit of charge and the unit of current
Command word guide:
- State: Give the unit or formula without explanation
- Calculate: Show working with correct units
- Explain: Give a reason — use "because" in your answer
- Describe: Say what happens step-by-step
