In a transformer, number of turns in primary coil are 140 and that of the secondary coil are 280 . If current in primary coil is $4 \mathrm{~A}$, then that of the secondary coil is (A) $4 \mathrm{~A}$ (B) $2 \mathrm{~A}$ (C) $6 \mathrm{~A}$ (D) $10 \mathrm{~A}$
In a transformer, the number of turns in primary and secondary are 500 and 2000 respectively. If current in primary is 48 A, the current in the secondary is (a) 12 A (b) 24 A (c) 48 A (d) 144 A
