Question

For the circuit given below, if the frequency of the source is 50 Hz, then a value of to which results in a transient free response is? (a) 0 (b) 1.78 ms (c) 7.23 ms (d) 9.21 ms This question was posed to me in a job interview. My question comes from Problems of Series Resonance Involving Frequency Response of Series Resonant Circuit in division Resonance & Magnetically Coupled Circuit 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

Correct choice is (b) 1.78 ms To explain I would say: For the ideal case, transient response will die out with time constant. T = \frac{L}{R} = \frac{0.01}{5} = 0.002 s = 2 ms Practically, T will be less than 2 ms.
