What are the applications of mutual induction?

Answers

1. The transformer- it converts an alternating voltage across one coil to a larger or smaller alternating voltage across the other. Since H.E.P is lost through transmission lines therefore it is stepped down before it being transmitted and stepped up again at the point of supply lines. In a step up transformer the number of turns in the secondary coil (Ns) is higher than the number of turns in the primary coil (Np). In a step down transformer the primary coil has more turns than the secondary coil. The relationship between the primary voltage and the secondary voltage is given by;
Np / Ns = Vp / Vs.The efficiency of a transformer is the ratio of power in secondary coil (Pp)m therefore efficiency = Ps/Pp x 100%
