Question:

A soldering iron uses an electric current in a wire to heat the tip. A transformer with 100 turns on the secondary coil provides 52 W at an RMS voltage of 26 V . Assume that the soldering iron is plugged into a 120 V outlet.

A) What is the resistance of the wire in the iron?

B) How many turns are in the primary coil?

C) What is the current in the primary coil?
