Transformers - Engineering

Q1:

In a certain loaded transformer, the secondary voltage is one-fourth the primary voltage. The secondary current is

A one-fourth the primary current

B four times the primary current

C equal to the primary current

D one-fourth the primary current and equal to the primary current

ANS:B - four times the primary current

In Any transformer input power = Output power.

i.e. Input(V*I) = Ouput(V*I).

- In case of Step down transformer, Voltage comes down and Current increases
same case these is.
