Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. In Faraday's first experimental demonstration (August 29, 1831), he wrapped two wires around opposite sides of an iron ring or "torus" (an arrangement similar to a modern toroidal transformer). This is the principle behind a transformer. Galvanometer Electromagnetic induction was discovered by Michael Faraday, published in 1831. The magnetic field lines are moving through iron transformer core and comprise the transformer secondary circuit..

The general expression for power factor is given by = / = where is the real power measured by an ideal wattmeter, is the rms current measured by an ideal ammeter, and is the rms voltage measured by an ideal voltmeter.Apparent power, , is the product of the rms current and the rms voltage. Once the core is heated, then there is some waste of electrical power, and transformer efficiency can be reduced. The reading of the wattmeter only represents the core and iron losses. If the load is sourcing power back toward the generator, then and will be negative. Transformer Below are the two simple formulas which can be used to find and calculate the rating of Single Phase and Three Phase Transformers..
