1. What is the current across the primary coil for each of the following transformers?
a) The input potential difference is 40 V, the secondary coil has an
output of 230
V
with a current of 13 A.
b) The primary coil has an input of 500 V, the secondary coil has an output of 400 V
with a current of 200 A.
c) The input potential difference is 33 V, the secondary coil has an output of 200 V
with a current of 50 A
d) The secondary coil has an output of 2kV with a current of 13 A. The input
potential difference is 340 V.
