In the supply-frequency equivalent circuit, the secondary e.m.f. is E 2, rather than sE 2, so to obtain the same current in this model as given by equation (1), we require the slip-frequency rotor resistance and reactance to be divided by s, in which case the secondary current would be correctly given by.

WebFaraday's law of induction. We'll move from the qualitative investigation of induced emf to the quantitative picture. As we have learned, an emf can be induced in a coil if the magnetic flux through the coil is changed. It also makes a difference how fast the change is; a quick change induces more emf than a gradual change. Weban e.m.f. is induced in the secondary because of the changing flux linkage. Iron is easily magnetised; its magnetic domains contribute to the strength of the magnetic field. It …
WebThe exact reason for induced EMF is the change in flux linkage with respect to the coil which continues until the movement of both magnet bar or coil is stopped. In other words, a strong magnetic field or flux won’t induce EMF in the static conductor. Hence, change in flux is the must have phenomena to induce EMF either in coil or conductors. WebIn a transformer, the coefficient of mutual inductance between the primary and the secondary coil is 0.2 henry. When the current changes by 5 ampere/second in the primary …
