In a step-up transformer the voltage in the primary is \( 220 \mathrm{~V} \) and the current is \( 5 \mathrm{~A} \). The secondary voltage is found to be \( 22000 \mathrm{~V} \). The current in the secondary (neglect losses) is
(A) \( 5 \mathrm{~A} \)
(B) \( 50 \mathrm{~A} \)
(C) \( 500 \mathrm{~A} \)
(D) \( 0.05 \mathrm{~A} \)
