When the collector current in a transistor is zero the transistor is?

Here the operating conditions of the transistor are zero input base current ( IB ), zero output collector current ( IC ) and maximum collector voltage ( VCE ) which results in a large depletion layer and no current flowing through the device. Therefore the transistor is switched “Fully-OFF”.

What is the most important fact about the collector current?

What is the most important fact about the collector current? It is measured in milliampere. It equals the base current divided by the current gain.

What is collector voltage?

[kə′lek·tər ‚vȯl·tij] (electronics) The direct-current voltage, obtained from a power supply, that is applied between the base and collector of a transistor.

Is the ratio of the DC collector current to the DC base current?

The ratio of the dc collector current (IC) to the dc base current (IB) is the dc beta (βDC) which is the dc current gain of a transistor. The ratio of the dc collector (IC) to the dc emitter current (IE) is the dc alpha (αDC).

What is collector cutoff current?

Collector cutoff current is the IC that still flows when the specified VC and a specified reverse bias is applied. It is normally less than either ICEO or ICER (collector current with the base open, or with the base resistively connected to the emitter).

What is the voltage across the collector to emitter terminal when the transistor is in I saturation II cut off III active region?

As the base current is zero, only small collector leakage current flows. The base emitter junction does not remain in the forward biased because the base current is zero. The collector to emitter voltage is equal to VCC….Cut off, Active & Saturation Region of Transistor.

Region	Base – emitter diode	Emitter – collector diode
Saturation	ON	ON
Active	ON	OFF

When the collector current increases What does current gain do?

05․ When the collector current increases, what does the current gain do? Decreases.

What is the voltage across the collector to emitter terminal when the transistor is in active region?

How is collector voltage calculated?

Determine the voltage drop between the collector and emitter junctions (Vce) of the transistor using the formula Vce = Vcc – IcRc, where “Vce” is the collector emitter voltage; “Vcc” is the supply voltage; and “IcRc” is the voltage drop across the base resistor (Rb).

What is the collector current?

The collector current, Ic, of a transistor is the amplified output current of a bipolar junction transistor.

How do you calculate voltage collector?

Why does collector current increase with base current?

Collector Current It increases for larger emitter currents because the larger number of electrons injected into the base exceeds the available holes for recombination so the fraction which recombine to produce base current delines even further. Use of the current gain beta.

What is the difference between collector voltage and emitter voltage?

The collector voltage, ( Vc ) must be greater and positive with respect to the emitter voltage, ( Ve ) to allow current to flow through the transistor between the collector-emitter junctions.

Why is the collector voltage of a bipolar NPN transistor positive?

Also the Collector supply voltage is positive with respect to the Emitter ( V CE ). So for a bipolar NPN transistor to conduct the Collector is always more positive with respect to both the Base and the Emitter.

What is meant by saturation voltage of the collector?

By “Saturation voltage” they mean the collector to emitter voltage under the given conditions. Usually it is with a forced beta of 10 or 20. In the datasheet segment you show it is with a forced beta of 50.

How to limit the maximum current flowing through a circuit?

The Collector is connected to the supply voltage VCC via the load resistor, RL which also acts to limit the maximum current flowing through the device. The Base supply voltage VB is connected to the Base resistor RB, which again is used to limit the maximum Base current.
