Measurement of a circuit incorporating what is thought to be an ideal op amp shows the voltage at the op-amp output to be -2.000 V and that at the negative input to be -1.000 V. For the amplifier to be ideal, what would you expect the voltage at the positive input to be? If the measured voltage at the positive input is -1.005 V, what is likely to be the actual gain of the amplifier?
