How do you measure apparent power consumption of a transformer (primary coil) with no load on secondary?

Lets say 120 Volts at 60 Hz with a Transformer across it with 1 Henry as the primary and 1 Henry on the secondary. The secondary has no load and is an open circuit. How would I physically measure the Apparent Power of the primary coil?

Side question, if secondary is shorted, will voltage across the primary head towards zero?
