A step-up transformer operates on a \( 230 \mathrm{~V} \) line and
P supplies a current of \( 2 \mathrm{~A} \). The ratio of primary and

W secondary windings is \( 1: 25 \). The primary current is:
(1) \( 12.5 \mathrm{~A} \)
(2) \( 50 \mathrm{~A} \)
(3) \( 8.8 \mathrm{~A} \)
(4) \( 25 \mathrm{~A} \)
