What is DC load line of a transistor?
A: A transistor has voltage gain as base current is allow to flow. If the load is constant then a DC mirror azimuth path can be plotted as a function of base current and collector current and that is the load line
Why is the base current in transistor very small?
Because a transistor's collector current is proportionally limited by its base current, it can be used as a sort of current-controlled switch. A relatively small flow of electrons sent through the base of the transistor has the ability to exert control over a much larger flow of electrons through the collector.
What happen if the base resistor of transistor has zero resistance?
If the base resistor of a transistor has zero resistance, it effectively creates a direct short circuit between the base and the power supply. This can lead to excessive current flowing into the base, potentially damaging the transistor and causing it to enter saturation, where it cannot function properly. Additionally, the transistor may overheat and fail due to the lack of current limiting. Therefore, a base resistor is essential for controlling the base current and ensuring safe operation.
What is vce and ie of a transistor?
A: Vce is the voltage across the transistor . Ie is the emitter current. Ico is the collector current with the base open. Or really the leakage.
How does a transistor amplify in a common emitter configuration?
The base is excited by a very low current. That turns the transistor on so that a higher amount of current flow comes out.
Why is the base of transistor made very thin?
Base of transistor is made thin just to get Collector current equal to Emitter current.
What will be the collector current of emitter base junction of a transister is reversed?
The question is poorly phrased and needs a grammatical cleanup. If you mean to ask "what happens to the collector-emitter current of a transistor when the emitter-base junction is reverse biased" then the answer is that the transistor will turn off, and you will only see leakage current.
How is current amplified in a transistor?
Transistor increase the strength of a weak signal from the base
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.
Is a diode like a transistor?
No. A diode is not like a transistor, and a transistor is not like (two) diode(s). Taken in isolation, the emitter-base and collector-base junctions of a transistor appear to be diodes, but they are coupled together so that the base-emitter current affects the collector-emitter current.
What is DC load line of a transistor?
A: A transistor has voltage gain as base current is allow to flow. If the load is constant then a DC mirror azimuth path can be plotted as a function of base current and collector current and that is the load line
Why the base current is responsible to turn on or off a transistor?
base current is very small and we should apply ainput on base current
How an n-p-n transistor can be used as a switch?
An n-p-n transistor can be used as a switch by controlling the current flowing through its base terminal. When a small current is applied to the base, it allows a larger current to flow from the collector to the emitter, turning the transistor "on." Conversely, when the base current is removed, the transistor turns "off," stopping the current flow. This on-off control allows the n-p-n transistor to effectively switch electrical circuits.
Why is the base current in transistor very small?
Because a transistor's collector current is proportionally limited by its base current, it can be used as a sort of current-controlled switch. A relatively small flow of electrons sent through the base of the transistor has the ability to exert control over a much larger flow of electrons through the collector.
What are the parameters of a transistor?
# parameter are usually the base current ib,collector current ic,emitter current ie,collector emitter voltagevce,base emitter voltagevbe,collector base voltagevcb which decide the operation &output of the transistor
What is the difference between common base emitter transistor and common base transistor?
Common base transistor if the emitter is open current Ie=0 but a small collector current thus exist.this current is reversed biased collector to the base voltage it is represented by Icbo while common emitter is d base terminal is open circuit and the base junction is reversed biased current Icbo flow from the tcollector to the emitter in the external circuit this current is called leakage current.
What does BC in electrical language mean?
In electrical terminology, "BC" typically stands for "Base Current." It refers to the current flowing into the base terminal of a bipolar junction transistor (BJT), which is essential for controlling the transistor's operation. The base current plays a crucial role in determining the transistor's current gain and overall performance in amplifying or switching applications.
