For an ideal operational amplifier (except for the fact that it has finite gain) one set of the value for the input voltages (v2 is the positive terminal v1 is the negative terminal) and output voltage (v0) as determined experimentally is v1= 2.01V, v2=2.00V and v0= -0.99V. Experiment was carried with different values of input and output voltages. Which of the following is not possible considering experimental error?

Operational Amplifiers topics include: Ideal operational amplifiers, inverting and non-inverting configuration, differentiators and differential amplifiers, operational amplifiers, finite open loop gain effect, circuit performance bandwidth and large signal operations. An operational amplifier (op-amp) is a high-gain electronic voltage amplifier that has a differential input and a single-ended output. It produces an output voltage by applying an open-loop gain to the difference between the voltage at the noninverting input terminal and the voltage at the inverting input terminal.  Op-amps...

An operational amplifier (op-amp) is a high-gain electronic voltage amplifier that has a differential input and a single-ended output. It produces an output voltage by applying an open-loop gain to the difference between the voltage at the noninverting input terminal and the voltage at the inverting input terminal. 

Op-amps are also known as instrumentation amplifiers. They are versatile and have many uses, including as a PID/PI controller in instrumentation. They are also used in high-quality imaging applications because of their high gain. 

An ideal op-amp has the following characteristics:
No distortion
No meaningful power
Infinite amplification
No noise
Infinite input resistance
Infinite frequency response
Accepts signals of any voltage
Infinite gain
Zero output impedance 

Practical op-amps draw a small current from each of their inputs due to bias requirements or leakage. 

Here are some other types of op-amps:
Inverting amplifier: The output voltage is expressed as a function of the input current.
Summing amplifier: An op-amp configured in a specific manner.
