What is the bias of a simplified common base (CB) amplifier configuration?

(a) Reverse biased

(b) Forward biased

(c) Forward and reverse biased

(d) It is independent of the bias

This question was posed to me in my homework.

My query is from Simplified Calculations for the CB Configuration in portion Low Frequency Transistor Amplifier Circuit of Electronic Devices & Circuits

Best answer
The correct option is (b) Forward biased

The explanation is: The common base design amplifier works to such an extent that the input signal is applied to the emitter terminal and the yield is taken from the collector terminal. The emitter current is likewise the input current, and the collector current is additionally the yield current. The base-emitter intersection is forward-biased.
