A power transmission line feeds input power at 2300
\( \mathrm{P} \)
\( \mathrm{V} \) to a step down transformer with its primary
W
windings having 4000 turns. The output power is delivered at \( 230 \mathrm{~V} \) by the transformer. If the current in the primary of the transformer is \( 5 \mathrm{~A} \) and its efficiency is \( 90 \% \), the output current would be
(1) \( 25 \mathrm{~A} \)
(2) \( 50 \mathrm{~A} \)
(3) \( 35 \mathrm{~A} \)
(4) \( 45 \mathrm{~A} \)
