Which has higher resistance emitter or collector?

as we know emitter is heavily doped and it has the highest resistance as compared to collector,so we have to employ trial and error method to detect BASE,EMITTER and COLLECTOR TERMINALS!!!

What is the difference between emitter collector and base?

The base is the gate controller device for the larger electrical supply. The collector is the larger electrical supply, and the emitter is the outlet for that supply. By sending varying levels of current from the base, the amount of current flowing through the gate from the collector may be regulated.

Why the base emitter junction has a higher forward voltage?

This forward voltage difference is due to the disparity in doping concentration between the emitter and collector regions of the transistor: the emitter is a much more heavily doped piece of semiconductor material than the collector, causing its junction with the base to produce a higher forward voltage drop.

Why the emitter-base junction is forward biased and the collector base junction is reverse bias?

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.

What is the size comparison between base emitter and collector?

This is because the work of the emitter is to supply charge carrier to the collector via the base. The size of the emitter is more than base but less than the collector. Base: The size of the base region is extremely small, it is less than emitter as well as the collector.

Why are the emitter base and collector of a BJT doped differently?

To improve the emitter efficiency and the common-base current gain (a), it can be shown that the emitter should be much heavily doped than the base. A low doping level of the collector increases the size of the depletion region. This increases the maximum collector-base voltage and reduces the base width.

Why is emitter always forward bias?

The emitter is always forward biased to enable the majority carriers to cross the emitter-base junction, so that current flows through the transistor.

Why is the base emitter junction forward biased in the common emitter configuration?

When output voltage VCE is reduced to a small value (0.2 V), the collector-base junction becomes forward biased. This is because the output voltage VCE has less effect on collector-base junction than input voltage VBE. As we know that the emitter-base junction is already forward biased.

How is the emitter base junction in the transistor biased?

In base emitter transistors the current is flowing forward biased, whereas, in collector and emitter transistors the current is passing in reverse biased. Thus, the emitter-base junction is forward biased and collector-base junction is reverse biased. The correct answer is option D.

How does emitter resistance affect stability and gain?

The aim of an AC signal amplifier circuit is to stabilise the DC biased input voltage to the amplifier and thus only amplify the required AC signal. This stabilisation is achieved by the use of an Emitter Resistance which provides the required amount of automatic biasing needed for a common emitter amplifier.

What is the working of emitter terminal in a transistor?

Working of Transistor Emitter: Emitter terminal is the heavily doped region as compared two base and collector. This is because the work of the emitter is to supply charge carrier to the collector via the base. The size of the emitter is more than base but less than the collector.

What is the collector-to-emitter resistance of a transistor?

Such being the case, then for any collector current there must be a resistance between the collector and emitter such that: Where R2 is the transistor’s collector-to-emitter resistance, E1 is the supply voltage, E2 is the collector-to-emitter voltage, and R1 is the load resistance. It is not really the proper question to ask.

What is the difference between base and emitter resistance?

The reason for this is the actual resistance as seen between base and emitter is dynamic and changes with DC bias and transistor gain: RB is the total extrinsic resistance connected to the base excluding a source Thevinen

How many junctions are there in a transistor?

The transistor as its names suggests transfer resistance from one channel to other channels. Thus, as there are three terminals of the transistor, i.e. base, emitter and collector. Thus, there are two junctions of the transistors.
