Transformer | Article about transformer by The Free Dictionary mutual flux Φ 0 produces the electromotive forces (emf's) e 1 and e 2 in the primary and secondary windings, respectively: e 1 = – w 1 dΦ 0 /dt, and e 2 = – w 2 dΦ 0 /dt, where w 1 and w 2 are the number of turns on the corresponding windings. The ratio e 1 /e 2 = w 1 /w 2 = k is called the turn ratio. The voltages, currents, and emf's (disregarding the emf's induced by the ...[email protected]
