When emitter base junction is forward biased and collector base junction is reverse biased the transistor is said to be at?
Active region is that region in which the emitter base junction is forward biased while the collector base junction is reverse biased.
When the emitter base junction is reverse biased then collector current?
Important Points:
| Mode | EB Biasing | Collector Base Biasing |
|---|---|---|
| Cut off | Reverse | Reverse |
| Active | Forward | Reverse |
| Reverse e Active | Reverse | Forward |
| Saturation | Forward | Forward |

Transistor biasing
| EMITTER JUNCTION | COLLECTOR JUNCTION | REGION OF OPERATION |
|---|---|---|
| Forward biased | Forward biased | Saturation region |
| Forward biased | Reverse biased | Active region |
| Reverse biased | Forward biased | Inverse active region |
| Reverse biased | Reverse biased | Cutoff region |
Why base-emitter is always forward biased?
The emitter is always forward biased to enable the majority carriers to cross the emitter-base junction, so that current flows through the transistor.
In which region are both the collector base and base-emitter junctions forward biased?
saturation region
Complete step by step answer: In the cut-off region both junctions are reversed biased and in saturation region both base-emitter and base-collector junctions are forward biased as in this region high currents flows as both junctions of the transistor are forward biased and bulk resistance offered is very much less.
Why emitter is forward biased?
Emitter is always forward biased w.r.t base so as to supply majority charge carriers to the base.
Is emitter forward biased?
Why is emitter always forward biased?
In which of the following emitter is forward biased?
transistor emitter-base junction
In a transistor emitter-base junction is always forward biased while the collector-base junction is reverse biased.
In which region are both collector base and base-emitter junctions forward biased?
In the saturation region the collector – base junction is biased and the base – emitter junction is biased for a transistor.
