(Summary description)The alternating current in the primary winding creates an electromagnetic field, and when the magnetic field changes, a current is induced in the secondary winding. Small transformers use enameled wire for their windings, while larger transformers use insulated copper tape. Transformers can be single-winding, center-tapped, or multi-tapped. The center tap has a terminal at the midpoint of the secondary winding, and its voltage is half the terminal voltage. Multi-tap has many terminals on the winding whose voltage depends on their position. The purpose of the iron core is to guide the electromagnetic field through the secondary winding. Silicon steel cores are used because of their high magnetic permeability. Insulating laminations work better than solid iron cores by limiting eddy currents, which reduces their losses.
