SUMMARY
The discussion clarifies misconceptions about current flow and voltage measurement in circuits, emphasizing that voltage is a difference between two points rather than a direct connection to ground. It introduces the Cockcroft-Walton voltage multiplier, which utilizes capacitors charged during alternate half-cycles to produce high-voltage outputs. The conversation stresses that current always travels in a closed loop, returning to its starting point, and challenges the notion that electricity inherently seeks ground.

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.
