Multiple choice:
The resistance of the primary coil of a well-designed, 110 step-down transformer is 1 Ohm With the secondary circuit open, the primary is connected to a 12 V ac generator The pnmary current is: essentially zero about 12 A about 120 A depends on the acutal number of turns in the primary coil
