Capacitors have input and output lines
Purpose of a capacitor between op amp input and output
As to how it works, the R11/R14 voltage divider from +5 yields 238mV at the non-inverting input to the op-amp and the op-amp drives the MOSFET gate to match that voltage at the inverting input, which requires 120mA to flow through the source in …
