CAPE Physics Unit 2 · 2010 · Paper 2 · Question 4(c)(ii)

Figure 3 shows a network of resistors and batteries with internal resistance 1 Ω for each battery.

Points a and b are connected by a wire of negligible resistance. Calculate the new value for the current that will flow through the 12 V battery.

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