During the normal operation of a transistor,
During the normal operation of a transistor,
Options
- Athe base-emitter junction is forward-biased
- Bthe base-emitter junction is reverse-biased
- Cthe base-collector junction is reverse-biased
- Dthe base-collector junction is forward-biased
Correct answer
C. the base-collector junction is reverse-biased
Step-by-step solution
For the normal operation of a transistor as an amplifier, it must operate in the active region.
In the active region, the base-emitter junction is always forward-biased to allow charge carriers to be injected into the base.
The base-collector junction is reverse-biased to collect the injected charge carriers efficiently.
Thus, the base-emitter junction is forward-biased and the base-collector junction is reverse-biased.
In the active region, the base-emitter junction is always forward-biased to allow charge carriers to be injected into the base.
The base-collector junction is reverse-biased to collect the injected charge carriers efficiently.
Thus, the base-emitter junction is forward-biased and the base-collector junction is reverse-biased.
