Electrical Machines I Prof. Krishna Vasudevan‚ Prof. G. Sridhara Rao‚ Prof. P. Sasidhara Rao 2 Basic Principles As mentioned earlier the transformer is a static device working on the principle of Faraday’s law of induction. Faraday’s law states that a voltage appears across the terminals of an electric coil when the flux linkages associated with the same changes. This emf is proportional to the rate of change of flux linkages. Putting mathematically‚ e= dψ dt (1) Where‚ e is the induced
