Q. The primary winding of transformer has 500 turns whereas its secondary has 5000 turns. The primary is connected to an ac supply of $20\ V,\ 50\ Hz$. The secondary will have an output of
A) $200\ V,\ 50\ Hz$
B) $2\ V,\ 50\ Hz$
C) $200\ V,\ 500\ Hz$
D) $2\ V,\ 5\ Hz$
Explanation
(a) $\frac{V_{s}}{V_{p}} = \frac{N_{s}}{N_{p}} \Rightarrow \frac{V_{s}}{20} = \frac{5000}{500} \Rightarrow V_{s} = 200\ V$
Frequency remains unchanged
