An autotransformer is supplied at 240V. If the secondary is tapped to give 60V with a load current of 12A, calculate the other two circuit currents and show the direction of current and voltages (5 marks)

Solution
V1 = 240V, V2 = 60V, i1 = 12A
(I)THE OTHER TWO CIRCUIT CURRENTS
From transformer ratio K = V1/V2 = i2/i1
240/60 = 12/i1
i1 = 60 × 12/ 240
i1 = 3A
Recall,
i1 = i2 + i3, i3 = [i2 – i1]
i3 = 12-3
i3 = 9A
