How does an op-amp differ from other amplifier suchas common emitter transistor amplifier?
A: They both use transistors. In actuality before an op amp becomes an op amp a discrete transistor made is made to provide it capabilities before it gets integrated into a substrate chip we call op amp. OP AMP have two input to work as a differential amplifier the input are bases closely match to provide virtual no voltage or current offset. Single ended amplifier has one input its reference is the signal source return.

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.
What number has 3 as its greatest common factor?
3 and any multiple of 3. Multiples of 3 that differ by 3.
What numbers has 5 as the greatest common factor?
Any multiples of 5 that differ by 5, like 45 and 50 or 120 and 125.
What is the difference while applying kcl to dc and ac circuits?
KCL is Common to both AC and DC. Only the waveform or AC and DC will differ
What two numbers have the greatest common factor of 4?
Any multiples of 4 that differ by 4. 4 and 8 8 and 12 12 and 16
How does power amplifier differ from a conventional voltage amplifier?
A voltage amplifier does not have to supply significant current bur a power amplifier does.
What does a transistor look like?
Transistor is a three terminal device. Its shape may differ with applications.
How does the non-inverting amplifier differ from voltage follower circuit?
altough voltage follower circuit provides output voltage which is in phase to input voltage as in noninverting amplifier but in unamplified form.
How does the transistor circuit differ from the thyristor circuit?
A thyristor is a "triggered" device. It will remain off until its gate electrode is made to conduct. It will then stay on (showing a very low resistance) until the power is removed, or (in Gate Turn Off devices) until a turnoff voltage is applied. A transistor can be used as a variable-resitance element. While it can be made to switch (like a thyristor) it does not need any special turn-off: just remove the input signal and it will go open circuit. A transistor can be made to respond to a vaying input signal with a varying resistance, so it can be used as a linear (analogue) amplifier.
What do all sodium isotopes have in common and how do they differ?
What they have in common is that they all have 11 protons in the nucleus.How they differ is that they have different numbers of neutrons in the nucleus.

What is the purpose of using a guitar y cable and how does it differ from a regular cable when connecting multiple instruments to an amplifier?
A guitar Y cable allows you to connect two instruments to a single amplifier input. It differs from a regular cable by splitting the signal from the instruments into two separate paths, allowing both instruments to be heard through the amplifier simultaneously.
Where does a SCR differ from a power transistor in operation?
thyristor can be scr or triac scr is strictly dc a triac is back to back scr's with a common gate two scr's back to back can be gated independently scrs cost less than triacs an scr can be combined with a full wave bridge to make an equivalent to a triac but this gives an additional 1.5V forward voltage drop
What's a combo amp and how does it differ from other types of amplifiers?
A combo amp is an amplifier that combines the amplifier and speaker in one unit. This differs from other types of amplifiers, like head and cabinet setups, which have separate amplifier and speaker components. Combo amps are more compact and easier to transport, making them popular among musicians who value convenience and portability.
How does preferred stock differ from common stock?
pay dividend before common stock
Can you replace a npn transistor by a pnp transistor?
Think of it this way: "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. If you have a NPN Transistor you can`t just replace it with an PNP as the polarities differ. If you can find a way to change those polarities then sure it could work. I would say it`s best go out and buy a few of both so you have a few, otherwise if the application of the transistor is not in a high-current or high-voltage circuit try and find another circuit with the required type of transistor. Absolutely most transistors can be replaced with other similar transistors. Different transistors have different conditions they work by so you should do some research and replace it with another that is either the same or have approximately the same data. Example 1: A burned transistor with the data NPN, 45Volt, 100mA, 0,3Watt, need to be replaced. It is a discontinued transistor, so unfortunately no original spare part can be found. Check the max voltage of the circuit where it was. If the voltage is close to 35 volt, then you may want to replace it with a higher voltage transistor. If it is lower, say max 20 Volt, then you should be able to replace it with a lower voltage transistor. Check the type of circuit where it was. If in an audio amplifier, then you should choose a 'low noise' audio transistor. Look at the NPN transistors you can get hold of and make your choice based on similar or more current, similar or more wattage, similar or lower or even higher voltage. Most small signal transistors are interchangeable if you follow these steps. Even most power transistors are interchangeable but you should make an extra effort and check/match the HFE Data on the transistor too. Normally no need for an exact match at all.
How expensive is a set of Crown amplifiers?
Crown amplifiers differ in price range depending on what kind you want. If you were to buy a new, small crown amplifier it would cost around 1000 dollars while a new, larger crown amplifier would cost around or above 2000 dollars. Crown amplifiers that are not new will likely cost less than a thousand depending on how complex and large the amplifier is.
