The ratio of the number of turns in the primary to the secondary of an ideal transformer is \(1:5\). If \(5\) kW power at \(200\) V is supplied to the primary, find
(i) current in the primary, and
(ii) output voltage.
Show Hint
For an ideal transformer:
\[
P_p=P_s
\]
\[
\frac{V_s}{V_p}
=
\frac{N_s}{N_p}
\]
\[
\frac{I_s}{I_p}
=
\frac{N_p}{N_s}
\]
Voltage increases in the same ratio as the turns, while current decreases in the inverse ratio.
