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

Analog meters measuring voltage will tap a tiny portion of the voltage through a resistor and put it across a meter movement- the meter moves the needle further when more voltage is applied.
Digital meters use a capacitor and measure how quickly that capacitor charges and discharges when the voltage is connected, along with an internal voltage reference.
