WORKING PRINCIPLE OF A TRANSFORMER

   WORKING PRINCIPLE OF TRANSFORMER  A transformer is a static (or stationary) piece of apparatus by means of which electric power in one circuit is transformed into electric power of the same frequency in another circuit. It can raise or lower the voltage in a circuit but with a correspond- ing decrease or increase in current. The physical basis of a transformer is mutual induction between two circuits linked by a common magnetic flux. In its simplest form, it consists of two inductive coils which are electrically separated but magnetically linked through a path of low reluctance as shown in Fig. 32.1. The two coils possess high mutual v inductance. If one coil is connected to a source of alternating voltage, an alternating flux is set up in v the laminated core, most of which is linked with the other coil in which it produces mutually-in- d u ced e.m.f. (according to Faraday’s Laws of Electromagnetic Induction e = MdI/dt). If the second coil circuit is close...
