19M.1A.SL.TZ2.20
Three resistors of resistance 1.0 Ω, 6.0 Ω and 6.0 Ω are connected as shown. The voltmeter is ideal and the cell has an emf of 12 V with negligible internal resistance.
What is the reading on the voltmeter?
A. 3.0 V
B. 4.0 V
C. 8.0 V
D. 9.0 V

D
Examiners report
Most candidates at both levels gave option A as the correct response instead of D. This would indicate that they have misread the diagram thinking the voltmeter was across the 1.0Ω resistor not the parallel combination.
