When emitter junction is reverse biased and collector junction reverse biased the transistor is said to be in region?

Saturation: Emitter diode and collector diode are on. Active: In the active region, the emitter diode is on and the collector diode is off. Collector base junction is reverse biased, whereas base emitter junction is forward biased. The transistor is said to operate in the active region.

When the emitter to base junction of a transistor is reverse biased collector current?

For digital purposes, or using a transistor as a switch, the base/emitter junction is reverse biased and the collector/base junction is reverse biased, electrons move away from one another resulting in a depletion region between the two areas and no current flows.

When the collector junction is reverse biased and emitter junction is forward biased the operating region of the transistor is called?

The transistor operates in the Active region when the emitter junction is forward biased and the collector is reverse biased in the NPN transistor.

When base-emitter junction and collector base junction are both reverse biased then transistor operates in?

If the collector-base junction and the base-emitter junction are both reverse-biased, then the BJT functions in the cut off region of the output characteristics.

Why emitter base junction is forward biased and collector base junction is reverse biased?

They combine enabling a current to flow across the junction. When a current flows between the base and emitter, electrons leave the emitter and flow into the base. In this way they are able to flow across what is effectively a reverse biased junction, and current flows in the collector circuit.

When the collector junction in transistors is biased in the reverse direction and the emitter junction in the forward direction the transistor is said to be in the?

Cut-off Region. The region of the output characteristics where both the junctions (emitter and collector) are reverse biased, is known as the cutoff region of the transistor. In order to cut-off the transistor, it is not enough to reduce lB to zero.

Why is Collector base junction reverse biased?

The collector is kept at a higher potential than base or emitter so that the collector can attract all the electrons from emitter in case of a npn transistor as an example. For this to happen the collector base junction is reverse biased.

Which of the junction in transistors will always remain reverse biased?

collector-base junction
In a transistor emitter-base junction is always forward biased while the collector-base junction is reverse biased.

Which transistor junction is always reverse biased?

base collector junction
In a transistor, the emitter base junction is always forward biased, whereas, the base collector junction is always reverse biased.
