A transformer consisting of 300 turns in the primary
\( \mathrm{P} \)
and 150 turns in the secondary gives output power of
W
\( 2.2 \mathrm{~kW} \). If the current in the secondary coil is \( 10 \mathrm{~A} \), then the input voltage and current in the primary coil are
(1) \( 220 \mathrm{~V} \) and \( 10 \mathrm{~A} \)
(2) \( 440 \mathrm{~V} \) and \( 5 \mathrm{~A} \)
(3) \( 440 \mathrm{~V} \) and \( 20 \mathrm{~A} \)
(4) \( 220 \mathrm{~V} \) and \( 20 \mathrm{~A} \)
