For a BJT, for common base configuration the input characteristics are represented by a plot between which of the following parameters?

(a) VBE and IE

(b) VBE and IB

(c) VCE and IC

(d) VCC and IC

The question was asked by my school principal while I was bunking the class.

The query is from BJT Configuration in chapter BJT Biasing of Analog Circuits

Best answer
Right choice is (a) VBE and IE

To explain: The input signal is applied between the base and the emitter terminals. Input current flowing is the base current and hence characteristics are represented by a plot between VBE and IB.
