CAPE Physics Unit 2 · 2004 · Paper 1 · Question 5(b)(ii)

A transformer shown in Figure 5 has 5000 primary turns and 100 secondary turns with a primary supply voltage of 120 V r.m.s. Connected across the secondary is a switch S and a 15 Ω resistor.

Calculate the currents in the primary and secondary windings when the switch is closed.

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