TRUE OR FALSE 1. Due to the infinite open-loop volatge gain of an ideal op-amp, its diferrential input voltage should approach zero for the output voltage to be finite. 2. An op-amp is a voltage amplifier circuit with very high gain, very high input resistance, and a very high output resistance. 3. The input resistance of an ideal op-amp is infinite resulting to the simplifying condition that the voltage at the non-inverting input is essentially equal to the voltage at the inverting input.

1. Due to the infinite open-loop volatge gain of an ideal op-amp, its diferrential input voltage should approach zero for the output voltage to be finite.
2. An op-amp is a voltage amplifier circuit with very high gain, very high input resistance, and a very high output resistance.
3. The input resistance of an ideal op-amp is infinite resulting to the simplifying condition that the voltage at the non-inverting input is essentially equal to the voltage at the inverting input.
4. For an op-amp differentiator circuit, if the input voltage is a sine wave then the output is also a sine wave that is in-phase with the input.
5. The gain of a non-inverting amplifier can be adjusted to values less than 1 or greater than 1 by using appropriate values of the external resistors.
