SUMMARY
The open loop voltage gain of an operational amplifier (op-amp) with an AC input voltage can be experimentally determined by ensuring that the inputs are at the same voltage when no input signal is present. The supply voltage for the op-amp in this discussion is +9V. It is crucial to utilize feedback to maintain this condition at DC levels while avoiding AC feedback interference. This method allows for accurate measurement of the op-amp's gain under specified conditions.
