What else can I help you with?
What is a difference between an operational amplifier and instrumentation amplifier and can you use one opamp to perform a same task as 3 opamp instrumentation amplifier?
An op amp is made from transistors, resistors and capacitors. It is enclosed in a "chip". A basic instrumentation amp is made of 2 op-amps. you can't have a single op-amp perform as good as a instrumentation amp, although it can perfrom the same task. An i-amp has much better CMMR (common-mode rejection) and a higher input impedance.
IC 741 is an?
It is an opamp chip consisting of 8 pins
How can transistors act as amplifiers or switches?
by creating two circuit loops
What are the two classifications of transistors?
The two basic types of transistors are the NPN transistorand the PNP transistor. Certainly there are many other semiconductor devices, but these are arguably the two basic ones.
Do transistors follow ohm's law?
As transistors are made of semiconductors, they do notfollow Ohm's law.A: they cannot follow exactly ohms law since they are themselves no linear active devices
Why output impedence is high in opamp?
Output impedance in an op-amp is not high - it is low - input impendance is high, and this is because the input stage transistors have high gain.

Are transistors semiconductors?
Transistors are made out of semiconductors, yes.
What are transistors made of?
Transistors are made from semiconductor materials. Silicon transistors are currently the most common.COMMONSiliconGermaniumGallium-Arsenide (GaAs)Silcon-GermaniumGallium Nitride (GaN)DiamondRARE
What happens if you connect two transistors parallel?
If you connect two transistors parallel it will heat up and be damaged.
Is a CPU made of transistors?
Yes it is!
Why base is used in transistors?
TWO
How do transistors relate to chemistry?
Transistors are made of materials. They have to be extracted and purified. This relies on chemistry and Materials Science.
What is the best electronic ever made?
transistors..
What are the two basic configurations in operational amplifier?
opamp is a device used to amplify ac as well as DC input signals. It is called as operational amp becoz it is used to perform all mathematical operations. Symbol of opamp indicates the direction of current.
What are the two main types of transistors?
The two main types of transistors are bipolar junction transistors (BJTs) and field-effect transistors (FETs). BJTs operate by controlling the flow of current via two types - NPN and PNP. FETs control current flow using an electrical field, with types including MOSFETs and JFETs.
What are transistors used for?
Transistors have two basic functions: # an electrically controlled electric switch # an electrically controlled "proportional valve" which can alter currents and voltages, or can amplify electric signals. Transistors can also be configured as Oscillators which provide an AC signal with constant frequency. Either an amplifier circuit or a switching circuit can be wired as an oscillator. Transistors can be used to form logic gates: And, Or, and Invert. Computers are made from logic gates, so computers can be made entirely from transistors. Transistors are in use in virtually all electronic devices. PC processors are composed of millions of tiny transistors. A transistor radio may have had only 6-10 transistors to enable operation. A late model car may have 10 to 15 computers comprised of thousands of transistors to perform all manner of operations in the vehicle.
