Why open loop configuration of opamp not used in linear applications?

Open loop means max amplification of an amplifier. if the open loop is very it will probably oscillate since there is not a feedback to control it or it will go to one rail of the other saturated

Why voltage gain is high in op amp?
A practical opamp is designed to approach the characteristics of the ideal opamp as closely as possible. The open loop voltage gain of an ideal opamp is infinite, so while this is actually impossible to achieve practical opamps are built with as high an open loop voltage gain as possible.
Why it is unsuitable for operational-amplifier to connect in open loop?
In open loop configuration the gain of the amplifier will be infinite, which in turn produces only square wave output.
The gain of an operational amplifier will be maximum?
A: the gain will be maximum at the open loop configuration and decrease as frequency increases
What are different applications of the diode?
Different applications of diode include:Rectification of voltageswitching circuitsclamping applicationsvoltage reference (zener Diode)phase lock loop/FFLinfrared applicationssignal amplifierssensorshigh frequency micro-wave oscillators.
What algorithm uses a loop to step through each element of an array starting with the first element searching for a value?
What you're describing is called a sequential search or linear search.
Why open loop configuration is not used for linear application?
becouse it is nt linear ... basicaly closs loop is linear .. and its loops
Is opamp a linear device?
A: It should be that is the normal operating mode. To be linear it strongly depends on negative feedback to maintain it into that linear region. By itself without any feedback it is very unstable due to the hi gain open loop availability
Why we don't prefer open loop configuration in case of linear circuit?
A: OPEN LOOP means the gain can be very high without the means to control the loop chances are that it will either saturate or oscillate

Why open loop amplifier configration are not used liner application?
Because they are not linear.
How 2prevent hacking?
Their is no way, all hacking is is finding loop holes in the configuration and exploiting them.
Why it is unsuitable for operational-amplifier to connect in open loop?
In open loop configuration the gain of the amplifier will be infinite, which in turn produces only square wave output.
The gain of an operational amplifier will be maximum?
A: the gain will be maximum at the open loop configuration and decrease as frequency increases
What is the reserved loopback IP address that can be used to test the configuration of the local IP device?
resever ip of loop back is 127.0.0.1
Formulas of a unity-feedback loop?
The formulas of a unity-feedback loop are: Closed-loop transfer function: This is the ratio of the output of the system to its input in the closed-loop configuration. It is calculated by dividing the open-loop transfer function by (1 + open-loop transfer function). Closed-loop gain: This is the gain of the system in the closed-loop configuration and represents the amplification of the input signal in the system. It is calculated by multiplying the open-loop gain by (1 + open-loop gain). Closed-loop bandwidth: This is the frequency range over which the system can effectively respond to input signals in the closed-loop configuration. It is usually determined by the pole locations in the system's transfer function.
