The characteristics shown by an element in the V-I curve is V=Is(1-e^-V/K). The nature of the element is _______(a) Non-linear, Bilateral, Passive(b) Linear, Unilateral, Active(c) Linear, Bilateral, Passive(d) Non-linear, Unilateral, PassiveI had been asked this question in an interview.The query is from Dynamic Braking of DC Shunt Motors topic in portion Braking of DC Motors & Induction Motors of Electric Drives
