As per faraday’s law of electromagnetic induction, where φ is the instantaneous alternating flux and represented as, as the maximum value of cos2πft is 1, the maximum value of induced emf e is, to obtain the rms value of induced counter emf, divide this maximum value of e by √2. The following equation is the fundamental relationship for an ideal transformer: Just put your finger on the “w” to find watts (output) = va x p.f., or “va”.
