CSEC Physics · January 2011 · Paper 2 · Question 3(b)(iii)

In the circuit shown in Figure 2, R₁ = 4Ω, R₃ = 8Ω and the supply is 24V. With switch S open, the current I through the ammeter is 2 A.

What is the reading on voltmeter (V)?

This question uses a figure or table from the paper — you'll see it when you practise.
