1. Voltage regulation of transformer is given by _____________ a) E2-V2/V2 b) E2-V2/E2 c) V2-E2/E2 d) V2-E2/V2 AnswerAnswer: b [Reason:] Voltage regulation is defined as change in the voltage or rise in voltage when transformer is load is thrown off. Thus, it is the difference of the no load voltage with the full load voltage…
