1.	Two coils X and Y have self-inductances of 5 mH and 10 mH and mutual inductance of 3 mH. If the current in coils X change at a steady rate of 100 A/s, the emf induced in coil Y is ____________(a) 0.3 V(b) 0.5 V(c) 1 V(d) 1.5 VI had been asked this question by my college professor while I was bunking the class.My query is from Series-Parallel Interconnection of Two Port Network topic in section Two-Port Networks of Network Theory
Answer» The CORRECT option is (a) 0.3 V Explanation: The emf is given by, V = M\(\frac{DI}{dt}\) = \(\frac{3}{1000}\) X 100 = 0.3 V Hence, the emf induced in coil Y is given by 0.3 V.
