Non-inverting and inverting op-amp simulation

01:41:12

Summary:
A simple simulation of two op-amps fed an identical signal with one configured in non-inverting mode (top) and the other in inverting mode (bottom).

Both op-amps amplify the voltage signal by the input signal by ~10x. The amount of signal amplification is dependent on the resistor feedback configuration and assumes a +/- voltage supply with sufficient difference  to fully amplify the signal (in this case +/- 20V). 

Example modifications: 
Altering the 10k ohm resistor on the top non-inverting amplifier to a 2k ohm leads to only a 2x signal amplification. The same phenomena occurs when you alter the 10k for the inverting amplifier.
