How's this.....

Your both right.

Current really is the killer, but it comes down to resistivity when it does the nasty business on someone. It's electron current flow that interupts your ticker.

Current is measured in amps and it appears the you guys over there use the terms interchangeably.

Resistance and current are inversely proportional if voltage is constant.

BTW Max, you have the equation for power correct. And higher voltages causes a dielectric breakdown of the skin. This produces perspiration and thus increases conductivity (less resistance, higher current). Result is usually cardiac arrest.
