Question

If the emitter-base junction is forward biased and the collector-base junction is reverse biased, what will be the region of operation for a transistor?

(a) cut off region

(b) saturated region

(c) inverted region

(d) active region

The question was asked at a job interview.

Question is from The Junction Transistor topic in section Transistor Characteristics of Electronic Devices & Circuits

Answer 1

Right option is (d) active region

The explanation is: When the emitter-base junction is forward biased and the collector-base junction is reverse biased, the transistor is used for amplification. A battery is connected to collector base circuit. The positive terminal is connected to the collector while the negative is connected to the base.
