How do you design hartley oscillator using transistor?
i will put tank ckt and give it to transistor via positive feedback
Where can you find IC UM66?
musical 3 pin IC UM66 and a popularly known Transistor BC548b
Video of transistor act as an amplifier?
pulse of positive voltage is not indicate to zero
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 output voltage on pin1 of UM66?
According to the datasheet the output on pin 1 of that transistor is a maximum 4.5 volts
What is the difference between upstream and downstream in electrical network?
Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.
What is Pin configuration of transistor sl100?
The pin configuration of sl 100 is B C E with ground as the base of the transistor.
What is the role of pnp and military?
PNP Positive Negative Positive, is a type of Transistor. I don"t know of military applications.
SL100 transistor's pin diagram?
transistor sl 100n has 3 pins and it is work like a switch. there is metal lead in the above metal surface the nearest pin is emeter and last pin is collector and center pin is base
How do you identify a pnp and npn transistor practically?
Using an ohmmeter on its lowest scale, the base-emitter junction of a transistor looks like a diode. If it conducts with the base positive, the transistor is an NPN. If it conducts with the emitter positive, the transistor is a PNP. (Of course, you need to know which probe of your ohmmeter is the positive one. DON'T assume anything. Some meters swing one way, some the other way. The only way to know for sure is to check it with another meter, used as a voltmeter.)

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.
Identification of transistors pins?
Identify Transistor Pin-outsWhich Pin Is Which on a BJT?Use this chart to find which pin is the base on a bipolar transistor and at the same time get a good idea of whether the transistor is faulty or good.(Don´t test FETs in this way though - handling FET pins can destroy the transistor!).Follow tests 1 - 3 then decide from the result which of the four arrows to follow. You may have to go through the test sequence more than once to make your diagnosis.
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
How can you test a transistor?
Testing Bipolar NPN or PNP transistorsIf you have an ohmmeter or continuity tester, it's not hard to check a Bipolar transistor. First, set your ohmmeter on "Diode" mode (or turn it to the lowest Ohms range.) Identify the transistor's Base pin. Next, for NPN transistors connect the ohmmeter's positive lead to the base. Briefly touch the other meter lead to the transistor's Collector, then to the transistor's Emitter. Both connections should show a low-hm's reading: a diode-type connection. Then, connect the meter's negative lead to the transistor Base, and again touch the other meter lead to each of the other transistor pins. The meter should show open circuit or infinite ohms on both pins, indicating reverse-biased diodes.If the transistor is PNP, just reverse the meter leads to perform the above tests. Touch the meter's negative lead to the Base pin, then verify that the Emitter and Collector pins behave as "turned on" diodes. Touch the meter's positive lead to the Base, and verify that the Collector and Emitter are acting like turned-off diodes.Testing for "transistor" function, locating the EmitterIf you use your wet fingers as a resistor, sometimes you can use your ohmmeter to check for amplifier function, and also detect which pin is the emitter. First test for diode function in order to locate the transistor's Base pin. Connect your ohmmeter between the other two pins (no connection to Base, yet.) Wet your fingers and touch the Base at the same time as one of the other pins. Note the ohms reading if any. Then touch your fingers between Base and the other transistor pin. Was one ohms reading much lower than the other? If not, then reverse the ohmmeter leads. Then touch your fingers between Base and one pin, then Base and the other pin. When you find one ohmmeter reading which is much lower than all the others, then you've located the proper polarity for transistor amplification. During the lowest ohms reading, your wet fingers were connected between Base and Collector. The other transistor pin then has to be the Emitter. (You can also perform this whole test more reliably by using a 1K resistor in place of your wet fingers!)Testing an FETIt's a bit more difficult, but FETs can be tested using an ohmmeter, a 9v battery, and wet fingers. (During low-humidity winter weather, when high static voltages are present, you might want to wear a grounding strap!) First let's test for correct operation of a common N-channel depletion-mode MOSFET. Connect your ohmmeter between the FET's Source and Drain pins, with the positive meter lead on the Drain. While watching the ohms reading, touch the 9V battery's negative terminal to the Source or Drain, then use your wet fingers to briefly connect the battery's positive terminal to the transistor Gate pin. The ohms value between Source and Drain should become low. Remove the battery and briefly touch your wet fingers between Source, Drain, and Gate. The ohms reading should go high again. You've just applied and removed a charge to the floating Gate pin, switching the transistor on, then off again.For testing a P-channel FET, just reverse all the polarities. Connect the ohmmeter to Source and Drain (positive meter lead to Source.) Use your wet fingers to touch the battery's negative terminal to the Gate pin (with battery positive touching Source or Drain.) That should make the ohms value go low.)NOTE ON ALL OF THE ABOVE: I assume that the transistor is disconnected from any other circuit. If your transistor is soldered into a circuit board, most of these tests won't work.
