Question

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 V I 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 Select the correct answer from above options network theory questions and answers, network theory questions pdf, network theory question bank, network theory gate questions and answers pdf, mcq on network theory pdf, gate network theory questions and solutions, network theory mcq Test , ies network theory questions, Network theory Questions for GATE EC Exam, Network Theory MCQ (Multiple Choice Questions)

Answer 1

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.
