Why a transistor can be operated in active region?

a transistor can only work in active region cox in active region collector base junction is in reverse bias and emitter base junction is in forward bias.

What arer the 3 legs of a transistor?

Emitter, Collector and Base cutoff region, saturation region, and liner region

Can you use transistor as diode?

its the simplest thing to do. There are three legs in a transistor, one each of collector, base and emitter. So if you need to use it as a diode, just connect either collector-base or emitter-base. Say, if you use an NPN transistor, then the base region will be the anode of diode and emitter or collector will be the cathode of the diode.

What does the base do in a transistor?

It depends on the transistor, you just have to look at the data sheet for the transistor.

How do you bias a 2N5777 photo-transistor?

connect the base of the transistor to a variable resistor and to a normal resistor

Is active is a cutoff region of transistor?

The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.

a transistor can only work in active region cox in active region collector base junction is in reverse bias and emitter base junction is in forward bias.

What are the majority carriers in the base region of an npn transistor?

holes are majority in base

What is cutoff region in transistor?

The cutoff region is when the transistor doesn't have sufficient base current to drive a larger current from emitter to collector. Therefore, the transistor does not turn on and stays shut off.

What arer the 3 legs of a transistor?

Emitter, Collector and Base cutoff region, saturation region, and liner region

What is breakdown region?

The breakdown region of a transistor is the region where the supply voltage, Vcc, becomes so large that the collector-emitter junction of the transistor breaks down and conducts, even though there is no base current.

What is the biasing technique in transistor for it to be in active region?

For a transistor to be in active region : Base Emitter junction should be forward biased and Emitter collector junction should be reverse biased.

What is the working of a transistor?

For proper working of a transistor,the voltage at the base region must be more positive than that of the emitter region.The voltage at the collector region, in turn, must be more positive than that of the base region.when voltage is applied to transistor, the emitter supplies electron,which is pulled by the base from the emitter as it is more positive than the emitter.This movement of electrons from emitter to collector creates as flow of electricity through the transistor.The current passes from the emitter to the collector through the base.Thus, adjustment of voltage in the base region modifies the flow of the current in the transistor by changing the number of electron in the base region. In this way, small changes in the base voltage can cause large changes in the current flowing out of the collector. We have three transistor element, a.)Emitter b.)Base c.)Collector

What do you mean by base-spreading resistance?

Base-spreading resistance refers to the resistance that exists in a bipolar transistor due to the spreading of the base current into the collector region. This resistance can limit the transistor's high-frequency performance and impact its overall efficiency. Reducing base-spreading resistance is important for improving the speed and performance of a transistor.

Why collector is made larger than base and emitter in a transistor?

Collector has larger area than base and emitter because base collector is reverse biased, hence the current flow here due to the minority carriers and the large power dissipation takes place by the majority carriers, this power dissipated in the form of heat.. To cool the device from heat we made the larger area........

What is power transistor base emitter voltage?

Its is the emiiter base of the transistor voltage!

What is saturation and active region in a transistor?

The output current of a transistor is controlled by the current in the 'base' input: Increasing the control current will increase the output current in a more or less linear fashion. In the saturation region, this is no longer true: The transistor is nearing the limits of how much current it can conduct, so increasing the control current further has little or no effect. When using a transistor as an amplifier, you want to stay away from the saturation region as it would distort the signal you are amplifying. When using a transistor as an on/off switch, as in digital circuits, being in the saturated region is 'on' and a normal mode of operation.
