1.	Calculate the value of the coefficient of coupling for the isolated coils.(a) 0(b) 1(c) 5(d) 7I had been asked this question by my college director while I was bunking the class.This interesting question is from Regenerative Braking of DC Shunt Motors in portion Braking of DC Motors & Induction Motors of Electric Drives
Answer» Right OPTION is (a) 0 Explanation: The COEFFICIENT of coupling EXPRESSES how the two coils are magnetically coupled. It is mathematically represented as K=M÷√L1.L2. For the isolated coils, the VALUE of the mutual inductance is 0. The value of the coefficient of coupling is 0.
