Question

Primary winding and secondary winding of a transformer has
100 and 300 turns respectively. If its input power is 60 W then output power of
the transformer will be

• A. 240 W
• B. 180 W
• C. 60 W
• D. 20 W

Answer 1

The correct option is C 60 W

Solution:- (C) $60W$

In a transformer-

$P_{\left(\text{output}\right)}=P_{\left(\text{input}\right)}$

Hence the output power of the transformer will be $60W$.
