When the base emitter junction is forward biased and the base collector junction is reverse biased?

For a transistor connected in common base connection, collector current is 0.95 mA and base current is 0.05 mA. Find the value of α : Q9. Current amplifiers are made of which type of semiconductor device?

When the emitter junction is forward biased while the collector junction is reverse biased transistor is at Region?

Transistor biasing

Why is Collector base reverse biased?

In its usual (active) mode of operation, the collector-base junction is kept reverse-biased to suck out the minority carriers that are injected continuously into the base via the emitter. Thus, the base potential is higher than the emitter potential but lower than the collector potential.

Why collector is always reverse biased with base?

Collector is always reverse-biased w.r.t base so as to remove the charge carriers from the base-collector junction.

What is the main purpose of the base collector junction?

The base–collector junction is biased to create a large electric field that removes and accelerates these carriers away from the base–collector junction and into the collector. It is normal convention to define the current direction as the same as the hole flow and opposite of the direction of electron flow.

How is the base collector junction of the transistor biased?

The biasing conditions are reversed so that the base collector junction is forward biased and the base emitter junctions is reverse biased, which switches the roles of the collector and emitter regions. The base contains a much lower reverse bias voltage than in the forward-active region.
