Transformer - Wikipedia
2 days ago · Ideal transformer equations. By Faraday's law of induction: =. . . (eq. 1) =. . . (eq. 2) Where is the instantaneous voltage, is the number of turns in a winding, dΦ/dt is the derivative of the magnetic flux Φ through one turn of the winding over time (t), and subscripts P and S denotes primary and secondary.. Combining the ratio of eq. 1 & eq. 2: Turns ratio = = =. . .
