When the both junction off NPN diode is reverse biased then the ddiode is in which mode?
When both junctions of an NPN transistor are reverse biased, the transistor is in the cutoff mode. In this mode, the transistor is effectively turned off, and it does not conduct current between the collector and emitter. As a result, the transistor behaves like an open switch, preventing current flow in the circuit.
Is a npn transistor a process or output?
An NPN transistor is a type of semiconductor device, specifically a bipolar junction transistor, and is not classified as a process or output. It serves as a fundamental building block in electronic circuits, functioning as a switch or amplifier. In this context, it can control current flow and signal amplification, but it itself is not a process or output.
Why same h parameter model is used for npn and pnp transistor?
The same h parameter model is used for npn and pnp transistors because gain is gain. It does not matter if you are using a negative or a positive system. So long as you are consistent in your calculations, you will get the correct results. In an NPN transistor operating in class A, if you increase the base current by increasing the base voltage, you will increase the collector current which decreases the collector voltage. In a PNP transistor operating in class A, if you increase the base current by decreasing the base voltage, you will still increase the collector current, which will increase the collector voltage.
Why NPN transistor are preffered?
You need a positive input to operate the transistor and since most circuits are negatively grounded when the transistor is not in use it has a negative input current thus using less power most of the time.
What is the result of carrier motion of forward biased junction of an NPN transistor?
In a forward-biased NPN transistor junction, electrons from the n-type emitter are injected into the p-type base, where they recombine with holes. This movement of charge carriers creates a flow of current from the emitter to the collector. As a result, a small input current at the base controls a larger output current flowing from the collector to the emitter, allowing the transistor to amplify signals. The overall effect is that the transistor can effectively switch or amplify electrical signals.
How is the NPN transistor different from the PNP transistor?
"P" is for Positive and "N" is for Negative So basically put a PNP Transistor Would use N to Switch P, in the name "PNP" or "NPN" the first character is for the polarity of the Collector-pin, the second for the Base-Pin, and the third for the Emmiter-pin. So if you have a PNP Transistor you can`t just replace it with an NPN as the polarities differ. If you can find a way to change those polarities then sure it could work. The Collector-pin basically receives the bigger current. The Base-pin determines how much of that current will be transferred to the emmiter-pin. So in a PNP the base current could for example be 0V and the Collector 5V, this will allow a free flow of current from Collector to Emmiter, the usage of a transistor in many cases is to switch high current with lower current. The main difference is that a PNP transistor uses "holes" as carriers and an NPN transistor uses electrons as carriers (It is to be remembered that the flow of current is always in the direction opposite to that of the flow of electrons). The difference in the symbol for the two transistors are that the PNP transistor will have an arrow pointed to the base from the emitter, and the NPN has it pointing outside.
Why emitter current flows away from base in NPN transistor?
arrows are shown for conventional current, not electron current.

2 transistor analogy for scr and derivation for expression of anode current?
a thyristor can be considered as two complementary transistors , one pnp- transistor, and other npn transistor
In a npn transistor does the collector current reach an upper limit as the base current gets smaller?
No. As base current decreases, so does collector current.
What are 2n2369 transistor?
What is a 2N2369 transistor.It's an npn switching transistor.
What is SL100?
It is an npn power transistor
Why npn transistor are more using than pnp transistor. Give two reasons?
1. NPN transistors current conductin is by electrons and conventional current flow will be in the opposite direction. 2. Majority charge carriers are electrons whose mobility is almost double than that of holes.
