Question

The base emitter voltage in a saturation region is_________

(a) greater than 0.7V

(b) equal to 0.7V

(c) less than 0.7V

(d) cannot be predicted

I have been asked this question in an interview for internship.

I need to ask this question from Transistor as a Switch in division Transistor Characteristics of Electronic Devices & Circuits

Answer 1

Right option is (d) cannot be predicted

Explanation: From the saturation mode characteristics, the transistor acts as a single pole single throw solid state switch. A zero collector current flows. With a positive signal applied to the base of transistor it turns on like a closed switch.
