An open feedback resistor (Rf) in an operational amplifier circuit can cause the output to rail to its maximum or minimum voltage levels, creating a square wave when it should produce a different waveform. This is because the feedback path is essential for controlling the output of the op-amp. Without it, the op-amp cannot properly regulate its output, leading to extreme voltage levels at the output.
