Problem
An ideal transformer has 360 turns on the primary coil and 45 turns on the secondary coil. The primary coil is supplied with an RMS alternating voltage of 110 V.
(1) Is the transformer a step-up or a step-down transformer?
(2) Calculate the voltage across the secondary coil.
(3) Suggest a possible use for the transformer in your home.
