Q:
For a transformer with primary turns 400, secondary turns 100, if 20A current is flowing through primary, we will get ___________
Answer & Explanation
Answer: A) 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.
