Answers to AQA GCSE Parallel Circuit Calculations(Physics)
Practice Questions
1.Calculate the resistance of each bulb in the circuit below.
V= IR
R = V/I
R = 9/3 = 3 ohms
2. The total resistance in the circuit below is 5 ohms. Calculate the potential difference of the cell in the circuit below.
In a parallel circuit, current splits at a junction, so total current is 14 A, 7 + 7 = 14 A.
V= IR
V = 14 x 5 ohms = 70V
3. In a parallel circuit, the potential difference across each component is 10V. The total current is 12A. The circuit contains only two bulbs and the cell. Calculate the resistance of each bulb.
Total current is 12A, so assuming both bulbs are equal, 6A flows through each bulb.
V = IR
R = V/I
R = 10/12 = 1.67 ohms.
