It depends on the transistor, you just have to look at the data sheet for the transistor.
connect the base of the transistor to a variable resistor and to a normal resistor
The input of a transistor is typically referred to as the "gate" in a field-effect transistor (FET) or the "base" in a bipolar junction transistor (BJT). In both cases, the input controls the flow of current through the transistor, allowing it to function as a switch or amplifier in electronic circuits. The gate or base receives the input signal that modulates the transistor's operation.
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
in a properly biased transistor, collector and emitter current also decrease
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
Its is the emiiter base of the transistor voltage!
The emitter, the base, and the collector are parts of a transistor.
Transistor increase the strength of a weak signal from the base
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.
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.
base
Base of transistor is made thin just to get Collector current equal to Emitter current.
If inceres the base voltage of transistor them it may be burn . The base volt may be 0.8v to 1.8 If it use as a amplifier
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.
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.
transistor. This word is a blended form of transfer of resistor. The legs of transistor (collector, emitter,base) transfer the resistance. So it is called as transistor
