Question

In a step-up transformer, the voltage in the primary is 220 V and the current is 5 A . The secondary voltage is found to be 22000 V . The current in the secondary coil (neglect losses) is, 5 A, 50 A, 500 A, 0.05 A

MARKS App · Accepted Answer

V s V p = I p I s ⇒ I s = I p × V p V s = 5 × 220 22000 = 0 .05 A
