For a transformer with primary turns 400, secondary turns 100, if 20A current is flowing through primary, we will get _________

A)
5A at secondary
B)
40A at secondary
C)
80A at secondary
D)
800A at secondary

Correct Answer : Option (C) :   80A at secondary

Explanation : Current in the primary of the transformer will get modified in the transformer secondary, according to the number of turns, in inverse proportion. Thus, turns are modified with 1/4 times the primary, we’ll get 4 times higher current at secondary.
