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 are the majority carrier in the base region of npn transistor called?
In an NPN transistor, the majority carriers in the base region are called holes. The base is made of p-type material, which means it has an abundance of holes (positive charge carriers) compared to electrons. This allows for efficient charge transport when the transistor is in operation, facilitating the flow of current from the collector to the emitter.
What is the meaning for sl100?
General Purpose Medium Power NPN Transistor
When an NPN transistor is properly biased then most of the electrons from the emitter -?
Emitter
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.
What are the similar transistor for 2SC2939 NPN?
2N2222
When an NPN transistor is saturated its Vce?
is zero
When a PNP transistor is connected in a circuit it can be used as a power amplifier because?
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
Is BT169 a npn or pnp transistor?
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
