How does common emitter transistor show more temperature variation than common base transistors?
A transistor is made up of two diodes back-to-back. In a common base circuit - the load is shared between two diodes
What is the minimum voltage required to turn on a pnp transistor?
If it's a germanium transistor, 0.3 volts. If it's the more common silicon transistor, slightly more than 0.6 volts.
What is the probability that the transistor will last more than 550 hours?
The answer depends on the type of transistor, how intensively it is used as well as the manufacturer.
Different between power transistor and transistor that used in small signal?
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
What is the most useful sense for an anteater in seeking out food?
Probably their sense of smell which is about 40 times more senstive than a human's sense of smell.
Is a vacuum tube far more stable than a transistor?
yes but vacuum tubes produce more sperm trololol
What is the major difference an NPN transistor and a PNP transistor?
The NPN transistor has its conduction curve where the base is more positive than the emitter, while the collector is also more positive than the emitter. The PNP transistor is exactly opposite, with its conduction curve where the base is less positive than the emitter, while the collector is also less positive than the emitter.
Do today's microprocessors have more transistor than those of 1970s?
Yes. Today's microprocessors have many, many times more transistors than those of the 1970's.
For normal operation of an npn transistor the base must be ground true or false?
False. For normal operation, an NPN transistor will have the base be more positive than the emitter and less positive than the collector, with the collector more positive than the emitter. Whether the base is grounded or not depends on the chosen design configuration of the circuit.
What is multi emitter transistor?
A bipolar junction transistor with 2 or more emitters. The most common use of these was in the input section of transistor transistor logic (TTL) gates. They offered significantly higher speed and used less area on the IC chip than the diodes used in the input section of the diode transistor logic (DTL) gates that came earlier. This made TTL ICs both faster and cheaper than the DTL ICs which soon became obsolete.
Why npn transistor are more using than pnp transistor give one or two reasons?
A; Main reason is because people like to think positive and the NPN needs a positive voltage to operate
Why the transistor is not used in switching 'AC voltage'?
The transistor is a "single direction current flow" device. Typically, for an NPN device, the collector must be more positive than the emitter for the device to bias on. You could use the transistor in an AC circult, but it would only conduct on half the cycle.
