The virtual Op-amp is found in the group Analog/ Analog_Virtual/ Op-amp_3T_Virtual. Look carefully at the symbol for the Op Amp. Be careful not to confuse the terminal labeled – with the one labeled +. The gain of the circuit is $APXVrAdKvScpAAAAABJRU5ErkJggg==$ . Measure and record the output on the multi-meter. Change R1 to 5kΩ and then to 10kΩ, in both cases measure and record the output on the multi-meter. Do your results match what you expect from the formula?

	R1 = 2k	R1 = 5k	R1 = 10k

Do results match? _____________________________________

Replace V1 with a function generator. The generator should be set to a frequency of 1 kHz and the amplitude should be 1Vp. Replace the multi-meter with the oscilloscope as shown below. For the case of R1 = 2kΩ attach a file with the Oscilloscope results. Note that when the input is less than zero the output is greater than zero. This is where the negative sign in the formula comes from.
