1.	The characteristics shown by an element in the I-V curve is V=I^2. The nature of the element is _______(a) Non-linear, Bilateral, Passive(b) Linear, Unilateral, Active(c) Linear, Bilateral, Passive(d) Non-linear, Unilateral, ActiveThe question was posed to me by my school teacher while I was bunking the class.This is a very interesting question from Regenerative Braking of DC Shunt Motors topic in portion Braking of DC Motors & Induction Motors of Electric Drives
Answer» Correct answer is (d) Non-linear, UNILATERAL, Active For explanation: The nature of the element is non-linear, unilateral and active. The shape of the CHARACTERISTIC is parabolic. For bilateral nature, it should be symmetrical in the first and third quadrant. Its SLOPE is negative in the SECOND quadrant which DETERMINES its active nature.
