Question

The resistance of the primary coil of a well-designed, 1: 10 step-down transfomer is 12. With the secondary circuit open, the primary is connected to a 12 V ac generator. The primary current is: (a) essentially zero (6) about 12 A (c) about 120 A (d) depends on the actual number of turns in the primary coil Select the correct answer from above options
