An opamp buffer circuit is one where the input signal is connected to the plus input, and the output is connected to the minus input. Within the performance limitations of the opamp, the output will track the input. The advantage of the buffer circuit is that is presents very little load impedance to the input signal, while providing a low impedance from the output to drive whatever circuitry is connected there.
A 741 Op-amp has three distinct parts and applications. They are a differential amplifier, a voltage amplifier, and an output amplifier.
If you go to the given link you will see the circuit of a current mirror using Op-Amp. And you can easily see how it is biased.
An opamp is a circuit of many components. It may either be built of many discrete components or be a single integrated component.
Vacuum circuit breaker is used in railway applications and as it is used in the applications where current chopping phenomenon is more
yes, with additional circuitry. an opamp wired as a differentiator followed by an opamp wired as a comparator can provide short timing periods. an opamp wired as an integrator followed by an opamp wired as a comparator, plus some other circuits left as an exercise to the reader can provide long timing periods.
A voltage buffer is a circuit that will buffer a source from an output.
Feedback resistance is used to feed back the current obtained at output back into the circuit. Thus a virtual ground concept is developed.this is majorly used in applications of OPAMP[IC 741].
A buffer amplifier is a type of operational amplifier that amplifies your input signal with a gain of 1 (so your output will be identical to your input, voltage-wise). Buffer amplifiers are used commonly due to having a very high input impedance. This means that loading effects (external factors that your circuit has to deal with) like large currents that could mess with your circuit otherwise, are avoided. A buffer amplifier is often used as the first stage of a circuit because it effectively isolates your circuit from loading effects.

An op-amp, or OPerational AMPlifier, is simply a pre-built transistor amplifier circuit on a self-contained integrated circuit chip (usually one chip holds multiple op-amps)
