8. In an inverting amplifier, the two input terminals of an ideal OP-AMP are at the same potential because.
9. The open-loop gain of the operational amplifier is 105. An input signal of 1 mV is applied to the inverting input with the non-inverting input connected to the ground. The supply voltages are ?10V. The output of the amplifier will be
10. When in a negative scaler, both RI and Rf are reduced to zero, the circuit functions as
