I only have one more chance at this problem and I can't understand why it isn't 1. I assumed that power in = power out and power = current x voltage. If the voltage remains constant, wouldn't the current as well?

"In the circuit shown, how many volts are impressed across and how many amps flow through the lightbulb?"

(120V ac)--> 100 turns -->10 turns [1 A] --> 10 turns --> 100 turns --> lightbulb
