The curve between the collector current versus the potential difference between the base and emitter is
(a) A straight line inclined to the axes
(b) A straight line parallel to the x-axis
(c) An exponentially varying curve
(d) A parabolic curve
I have been asked this question in an interview.
My enquiry is from BJTs Current-Voltage Characteristics topic in chapter Bipolar Junction Triodes (BJTs) of Electronic Devices & Circuits
