How does this voltage multiplier work?

Current does not simply disappear upon meeting ground; rather, voltage is a difference between two points, with ground serving as an arbitrary reference point. Current flows in a closed loop, returning to its starting point. The Cockcroft-Walton voltage multiplier operates by charging capacitors on alternating half-cycles, effectively creating high-voltage outputs in series. It's important to understand that electricity does not inherently seek ground, as demonstrated by measuring voltage between a battery's positive terminal and a grounded object, which can show 0V. Understanding these concepts is crucial for grasping how voltage multipliers function.

No that is a misconception. Voltages are always voltage difference between two points. The ground symbol just identifies the arbitrary place that we label zero volts. If you always remember to name the two points where you measure voltage, then you can remove the ground symbol from the circuit.
The important thing to remember is that current always flows in a closed path, back to the point where it started.

Look up ‘Cockroft-Walton voltage multiplier’. The caps are charged on alternate half-cycles and end up behaving like high-voltage cells in series. The high voltage output is between 4Us and the ground symbol.MasonJ1989 said:
And delete the concept that ‘electricity always wants to go to ground’ from your cortex... Check the voltage between a battery +ve and a grounded metal pipe. 0V.
