Question

If a voltage from 120V in a primary circuit of a transformer is reduced
to 60V in a secondary circuit:

a) the number of loops in a primary circuit is twice the number of
loops in a secondar circuit
b) the current through secondary circuit is twice of the current
through primary circuit
c)both a) and b)
d)none of the above

and Why?

Explanation / Answer

answer -------> c)both a) and b) as in a transformer, voltage is directly proportional to the number of turns, so, number of loops in a primary circuit is twice the number of loops in a secondary circuit. as power remains constant in both the secondary and primary, as voltage increases,current decreases, so, current through secondary circuit is twice of the current through primary circuit
