The coils of a step down transformer have `500` and `5000` turns. In the primary coil an ac of `4` ampere at `2200` volts is sent. The value of the current and potential difference in the secondary coil will be.(Assume `100%` efficiency for the transformer)
A. 20A, 220 V
B. 0.4 A, 22000 V
C. 40 A, 220 V
D. 40 A, 22000 V
