The current in the primary coil decreases, and the power being supplied by the wall socket decreases.

Explanation:

In this case the current in the primary coil decreases, and the power being supplied by the wall socket decreases because as resistance across the secondary coil increases, the current and power decreases. This is because the current in the secondary coil is inversely proportional to the power and current in the primary coil.
