Question

An ideal transformer converts 220 V AC to 3 . 3 kV AC. It transmits the power of 4 . 4 kW . If the primary coil has 600 turns, then alternating current in the secondary coil is, 1 3 A, 4 3 A, 5 3 A, 7 3 A

V i n = 220 V, V o u t = 3.3 × 10 3 V P o w e r = 4.4 k W N p = 600 P = V i n × I i n . I i n = 4.4 × 1000 220 = 44 × 10 22 = 20 A e s e p = I p I s I s = I p = e p e s × 20 × 220 3.3 × 1000 = 44 33 = 4 3 A
