The op-amp is the fundamental building block of analog electronics. With negative feedback, its gain is set entirely by external resistors: an inverting amp gives −R2/R1, a non-inverting amp 1+R2/R1. An integrator uses a feedback capacitor to output the running integral of its input.

Governing equation

A = - \frac{R _{2}}{R _{1}} = - \frac{100}{10} = - 10.00 \times

Reading this result: Inverting gain is −R2/R1 = -10.00×: the output is a scaled, flipped copy of the input, set entirely by the resistor ratio.
