Every time I look this up I am being shown how to use a Multimeter. But I want to know WHAT exactly is that multimeter doing? It is looking at the potential difference? But what exactly are the components doing inside. What would the simplest Multimeter look like

Simplest is a meter movement (coil, magnet and needle) with a resistor in series. The meter directly measures current (current in coil creates magnetic field which moves needle), but the resistor converts voltage to current.
Fancy meters have more to them and are thus able to perform better in various ways. But that’s the basic idea.
