A step-down transformer has 50 turns on secondary
\( \mathrm{P} \) and 1000 turns on primary winding. If a transformer

W is connected to \( 220 \mathrm{~V}, 1 \mathrm{~A} \mathrm{AC} \) source, then what is output current of the transformer?
(1) \( \frac{1}{20} A \)
(2) \( 20 \mathrm{~A} \)
(3) \( 100 \mathrm{~A} \)
(4) \( 2 \mathrm{~A} \)
