If in a transistor both collector-base and base-emitter junctions are reversed biased then it is:
Correct answer: A. Cut-off region
- A. Cut-off region
- B. region Act
- C. Active region
- D. point
Explanation
In a typical operation one junction (the base-emitter junction) is forward biased while the other (the base-collector junction) is reverse biased.However, if both the collector-base and base-emitter junctions are reverse biased, the transistor is in the cutoff state. In this state, both junctions are blocking the majority carrier current flow, which means there is minimal current flowing through the transistor.

About PN Junction
A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
