A transistor is in active region when?
a transistor in active region when emitter junction is forward biased nd collector junction is reverse biased
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.
What is common collector bipolar junction?
A circuit in which the input signal is applied to its base and the collector is earthed (grounded) is known as common collector configuration of BJT (BiPolar Junction Transistor)
What bias conditions must be present for the normal operation of a transistor ampilifier?
Assuming you mean a bipolar junction transistor (BJT): 1. Reverse bias on the collector-base junction. 2. Forward bias on the base-emitter junction, that is 3. Sufficient to give the correct operating point of collector voltage/collector current.
What is the biasing technique in transistor for it to be in active region?
For a transistor to be in active region : Base Emitter junction should be forward biased and Emitter collector junction should be reverse biased.
Why do you have to connect a resistor to collector of transistor?
Type your answer here... to properly bias the junction for current flow thru the transistor. The voltage potential must be different on the base than the collector
A PNP transistor is connected in a circuit so that the collector-base junction remains reverse biased and the emitter-base junction is forward biased This transistor can be used as a power amplifier?
Yes1
Why a transistor can be operated in active region?
a transistor can only work in active region cox in active region collector base junction is in reverse bias and emitter base junction is in forward bias.
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.
What separates the three regions in a BJT?
Two junctions namely emitter-base junction and collector-base junction separates regions in a transistor.
What is PNP?
it is a bipolar junction transistor having p-type emitter & collector terminal and , n-type base terminal .
Why is the collector of a transistor connected to the base or heatshink?
Because most of the heat buildup occurs in the reverse biased collector-base junction where Ic = Ie + Ib flows.
