An op amp, short for operational amplifier, is an electronic device that amplifies the difference between two input signals and outputs the amplified signal.
An inverting op amp means that the output signal is a mirrored or inverted version of the input signal. This is achieved by placing the input signal at the inverting input terminal and providing feedback from the output to the inverting input terminal.
No, Vout will not go to zero in this scenario. The op amp will try to maintain a virtual ground at the inverting input, causing the output to reach a stable voltage that is not necessarily zero.
Yes, in this case Vout will go to zero. The op amp will try to maintain a virtual ground at the inverting input, causing the output to reach a voltage of zero to balance the difference between the two inputs.
If the difference between the inputs is large, the op amp may saturate and the output will reach the maximum or minimum voltage that it can provide. This can cause distortion in the output signal and should be avoided in most applications.
