The transistor operates in the Active region when the emitter junction is forward biased and the collector is reverse biased in the NPN transistor. For any amplification, (voltage or current), the transistor should be operated in the active region.

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

Solution : In a transistor, if emitter is reverse biased and collector is forward biased, then the emitter will work as collector and the collector will work as emitter.

When emitter junction is forward biased and collector?

the base emitter junction is forward biased and the base collector junction is reverse biased. When a current flows through the base emitter junction, a current also flows in the collector circuit. This is larger and proportional to the one in the base circuit.

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

No current will follow into the base when the emitter-base junction of a transistor is reverse biased. When no current is flowing into the base, no current will flow in the collector. Now if the collector is also reverse biased, then the collector current will flow. This is called reverse active biasing.

Why emitter is forward biased and collector is reverse biased?

Working of NPN Transistor

As shown in the above figure, the emitter to base junction is forward biased and the collector to base junction is reverse biased. Forward bias on the emitter to base junction causes the electrons to flow from N type emitter towards the bias. This condition formulates the emitter current (I_E).

The emitter base junction is forward biased and the base collector junction is reverse

When emitter to base is reverse biased and collector to base is forward 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.

Why the emitter base junction is forward biased and collector-base junction is reverse biased what will be the region of operation for a transistor?

Hence, if the emitter-base junction is forward biased and the collector-base junction is reverse biased, the region of operation for a transistor will be active region.

When the collector base junction is properly reverse biased and remains constant which results in?

VKnee, the collector-base junction is properly reverse biased and the value of β remains constant, resulting in faithful amplification. If no bias were used, the device would initially be completely off, resulting in a Q-point at A- namely, zero current through the device (and zero voltage across it).

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.

When a junction diode is reverse biased what causes current across the junction?

EXPLANATION: When the p-n junction is reverse biased, then the current across the junction is mainly due to the drifting of minority carriers.

What is forward bias and reverse bias in transistor?

In forward biasing the positive terminal of the battery is connected to the p-region and the negative terminal is connected to the n-type material while in reverse bias the positive terminal of the supply is connected to the n- type material and the negative terminal is connected to the p-type material of the device.

When the transistor is in reversed biased condition?

If you reverse bias the diode, the diode cuts off. Now, the base-emitter junction in a transistor is going to essentially turn the transistor on or off. Now, the base-collector junction will not have that same power, but the base-emitter junction will determine whether the transistor is turned on or off.

When PN junction is said to be reverse biased what will be the direction of flow of majority charge carriers?

PN junction diode doesn't operate in reverse biased. In reverse bias, the depletion region expands and stop the flow of majority carriers.

When PN junction is reverse biased what will be the direction of flow of majority charge carriers?

Solution : When a p-n junction is reverse biased, then the majority charge carriers cannot cross the junction. So, no forward current flows. But in reverse direction, a feeble current flows which is known as reverse saturation current.

When pn junction diode is reverse biased then the width of the barrier potential?

The width of the depletion layer in a p-n junction diode increases in reverse bias as charge carriers are swept into battery terminals, holes from p-type into negative terminal and electrons from n-type into positive terminal. Due to large number of ions in depletion region, its potential increases.

When CB junction of a transistor is reverse biased and other junction is not biased then it will?

If both junctions are reverse biased the transistor is switch off since the currents will be very small in the order of the reverse saturation current and the reverse is true that is the transistor will be switch on and saturated when the 2 junctions are forward biased.In this case the transistor currents are ...

When input circuit of transistor remains forward biased and output circuit remains reverse biased then it is known as?

When input circuit of a transistor remains forward biased and output circuit remains to reverse biased, then it is known as transistor biasing.

Which junction is forward biased when transistor is used as an amplifier?

A transistor acts as the amplifier in an active region. In the active region, the emitter-base junction of the transistor is forward biased and the collector-base junction is reverse biased.

What is emitter feedback bias?

The emitter feedback bias uses the same overall idea as the collector feedback circuit, namely, that changes at the output will be reflected back to the input and thus help mitigate the initial change.
