Question

when both the junction of transistor are forward biased then the transistor is said to be in. region​

Answer 1

When emitter junction is forward biased and collector junction is reverse biased then a p-n-p transistor is said to be in active region of operation.

Answer 2

When both the junction of transistor are forward biased then the transistor is said to be in saturation region.

• A saturation area is when a transistor starts to act like a closed switch.

• The transistor's collector and emitter are effectively shorted.

• In this mode of operation, the collector and emitter currents are at their highest.

• When both the emitter and collector junctions are forward biased, the transistor functions in the saturation zone.

• In this scenario, the saturation region of a transistor behaves like a switch.
