How is a current induced in a secondry coil related to current in primary coil |
| Answer» In mutual induction current will be induced in both the primary and secondary.Let i1 be the current in the primary coil M21 represents the mutual induction of 2ndary coil w.r.t. primary coil.Thus emf developed in the 2ndary coil due to current in primary will beE21 = - M21di1 /dtDue to the emf a current i2 is developed in the 2ndaryemf developed in the primary coil due to current in 2ndary will beE12 = - M12di2 /dtWe have M21 = M12 | |
