What else can I help you with?
What happens when the base current of a transistor is decrease?
in a properly biased transistor, collector and emitter current also decrease
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.
How do you reverse bias base collector junction?
To reverse bias a base-collector junction in a bipolar junction transistor (BJT), you need to apply a positive voltage to the collector relative to the base for an NPN transistor (or a negative voltage for a PNP transistor). This involves connecting the collector terminal to a higher potential and ensuring the base terminal is at a lower potential. As a result, the depletion region at the base-collector junction widens, preventing current flow between the collector and base. This condition is essential for transistor operation in certain configurations, such as in cutoff mode.
Who collector base current when emitter is off?
When the emitter of a bipolar junction transistor (BJT) is off, the collector-base junction is typically reverse-biased, meaning that the collector current is minimal or negligible. In this state, the collector-base junction does not conduct significant current because the emitter does not provide carriers to the base. As a result, the collector current is effectively zero, and the transistor is in its cutoff region.
What arer the 3 legs of a transistor?
Emitter, Collector and Base cutoff region, saturation region, and liner region
What happens when the base current of a transistor is decrease?
in a properly biased transistor, collector and emitter current also decrease
What are the parts of a transistor?
The emitter, the base, and the collector are parts of a transistor.

What is darlington configuaration?
A Darlington pair uses two transistors connected to behave as a single transistor with a very high current gain (beta). Transistor-1 has its collector connected to the collector of transistor-2. Transistor-1 has its emitter connected to the base of transistor-2. The base of transistor-1 with the emitter and collector of transistor-2 is used as a single transistor.

Bc stands fo what in transistor?
base to collector
What are the three terminals of a transistor?
Emitter, Base, 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
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 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 do you know if a transistor is a PNP or an NPN?
To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
Why is the base of transistor made very thin?
Base of transistor is made thin just to get Collector current equal to Emitter current.
