physics

300 V, 15 A

450 V, 15 A

450 V, 13.5 A

600 V, 15 A

Explanation

To solve this problem, we need to find the voltage across the secondary coil and the current in the primary coil of a transformer. $\\$ Given: $\\$ • Efficiency of the transformer $\eta = 90\% = 0.9 \\$ • Primary voltage $V_p = 200$
