The conduction loss versus device current characteristic of a power MO

1.	The conduction loss versus device current characteristic of a power MOSFET is best approximated by a ________(a) Straight line(b) Rectangular hyperbola(c) Parabola(d) Exponential decaying functionsI got this question during an online interview.The doubt is from Modified Speed Torque Characteristics of DC Shunt Motors in section Characteristics of DC & AC Motors of Electric Drives
Answer» RIGHT choice is (C) Parabola The explanation is: A MOSFET in ON state BEHAVES as RESISTANCE so the conduction power loss is given by, P=I^2R. Hence, the power vs current curve will be a parabola.
