Worked Solution & Example Answer:A student experiments with filament lamps in a circuit - Edexcel - GCSE Physics - Question 4 - 2017 - Paper 1
Step 1
Identify the circuit allowing current and voltage measurement
Answer
Among the circuits provided, Circuit D allows for measuring both the current and the potential difference across the lamp. In this configuration, an ammeter is placed in series to measure the current, and a voltmeter is placed in parallel to measure the potential difference across the lamp.
