V is the instantaneous voltage. N is the number of turns in the winding. dɸ / dt is the change in magnetic flux (ɸ) through the windings over time. P and S refer to the Primary and Secondary windings respectively. The V/N ratio for an ideal transformer is given by: V1/N1 = V2/N2 This equation… Read More

A Transformer is a device that changes the voltage of alternating current (AC). The transformer is the key component in power transmission and distribution. It steps up the voltage to high levels for long-distance transmission and then steps it down again for local use. The first transformers were built in 1885 by George Westinghouse. He… Read More
