Opamps (Part 1) Inverting & Non-Inverting Voltage Gain Derivation - Simplest Explanation.

The simplest possible derivations for the inverting and non-inverting configurations of an operational amplifier are presented. Assumptions are presented which make these derivations possible at the start of the video. In practice, there will be small differences between the 'ideal' due to bias currents, tolerances etc. Hopefully, this short video will help you in understand the basic operation of these configurations.
