What should be the value of capacitor at transistor amplifier circuit input?
at full input, if the transistor is working, the value of capacitor will be 0.
When testing transistors how much minimum voltage difference should be seen across the base-emitter junction?
It depends on the transistor. Minimum base-emitter junction voltage can be as low as 0.6 volts for a silicon transistor, and as low as 0.2 volts for a germanium transistor.
How do you determine the maximum Wattage of a transistor from its canister markings. Specifically a B22M TCG102A. Any standards websites you could recommend. Thanks.?
It is very difficult to identify transistor watts from the package, due to the increase in dissipation that can be obtained from a heat sink -- not normally provided with the transistor. In your case however, the TCG102A should cross reference to the standard ECG line of electronic components. Find the ratings you seek by searching for the electrical characteristics of the ECG-102A transistor.
What damage it does to transistor operation?
Transistor failure can occur due to a variety of reason. The following are some of them. Age Aging of transistor due to temperature variations inside the components due to carrying current can cause failure. The electrical properties of the materials inside can drift due to age. External Causes External causes such as spikes in the power supply, heat, mechanical damage can also result in transistor failures. Hence, all transistors should be adequately protected against overvoltage. Poor Circuit design. Improperly chosen components and wrong circuit design can also result in transistor failure. Hence, all components in the circuit should be properly rated with sufficient allowance for overloading and temperature rise. The failure of one component can lead to cascade failures of other components. Overheating Overheating is the most common cause of transistor failure. Hence, it is important that transistors be provided with cooling mechanism. Devices which contain temperature-sensitive electronic components should be kept in air conditioned environments. Electrostatic Discharge Electrostatic discharge can also damage transistors. Hence proper precautions against Electrostatic Discharge Should be taken.
What is TTL logic family?
To know about the advantages of TTL logic family, one should have a basic idea about RTL, DTL etc. Diode logic (DL) uses diodes to implement logical functions like AND and OR. But the disadvantage is that it can not perform NOT operation. As AND and OR are not complete functions by themselves, they can not perform several logic functions without NOT. Hence, there was a need for some device which can perform a NOT function as diodes can not. That device is a transistor. Then came the DTL which uses a transistor along with diodes. As a transistor can act as an inverter, NAND (NOT-AND) & NOR (NOT-OR) operations can be performed. But this logic uses several diodes which will slow down its operation. Due to the delay offered by them, the logic levels may sometimes change i. e. 0 t0 1 or 1 to 0. Then came TTL. This logic uses a multi emitter transistor, a transistor with many emitter terminals. As every emitter is nothing but a diode, this logic eliminates the use of all diodes. This is the major advantage. As transistor becomes ON and OFF much rapidly than a diode, switching time will be faster. TTL, or Transistor-transistor logic replaced resistor-transistor logic, and used much less power. The TTL family is very fast and reliable, and newer faster, less power-consuming, etc. types are always being developed. = In TTL (Transistor-Transistor Logic), think that the device using this technology is made from several transistors. Another advantage is that many more chips employ this technology.
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.
Should op amp remain in active region for virtual ground?
An op amp must remain in its active region for virtual ground to be preserved.
What is the umbilical region?
I believe the question should have been " What is the umbilical region? If that was the question , then with reference to mammals-- The umbilical region is a small area of of about two inches' radius with the centre at the centre of the navel. Navel is another term for the umbilicus. The umbilicus represents the point at which the umbilical cord of placental mammals was connected to the mother'womb before birth.
How should the two transistor junctions be biased for proper transistor amplifier operation?
Emitter-Base junction should be forward biased.Collector-Base junction should be reverse biased.
What should be the value of capacitor at transistor amplifier circuit input?
at full input, if the transistor is working, the value of capacitor will be 0.
Why transistor is used as an amplifier?
A transistor acts like a valve or gate that opens and closes, and allows a current to flow. Since the amount of current that flows is controlled by another input, they can be used to make amplifiers. Carbon microphones and vacuum tubes have the same property, and so have also been used to make amplifiers historically.
How do you get game centre on an iPod touch?
you shouldnt have to get game centre it should only be on there
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.
When testing transistors how much minimum voltage difference should be seen across the base-emitter junction?
It depends on the transistor. Minimum base-emitter junction voltage can be as low as 0.6 volts for a silicon transistor, and as low as 0.2 volts for a germanium transistor.
Arizona and New Mexico are in a region which region should they be in?
They are in and should be in the Southwest Region.
Please Suggest equivalent transistor for AC 128.but it should not germanium transistor?
You can consider using the silicon transistor 2N3904 as an equivalent for the AC128. The 2N3904 is a general-purpose NPN transistor commonly used in various amplifier and switching applications. Remember to check datasheets and specifications to ensure compatibility with your circuit requirements.
What should be the value of Vce if the base terminal of a transistor is open?
It would be zero because there is a leakage.
