Not so far. The highest voltage yet attained for current electricity is 5 million volts: The highest electrical potential ever produced by man, over 5,000,000 volts, has been achieved in the laboratory of Dr. Gregory Breit and Dr. M.A. Tuve at the Department of Terrestrial Magnetism of the Carnegie Institution of Washington.
Voltage is the measure of the strength of an electrical source (for a given current level). Rechargeable batteries for power tools generally contain cells with a voltage of 1.2V, 1.5V or 3.6V.atteries that have a voltage between 14.4V and 36V are manufactured for use on heavier duty tools such as cordless hammer drill drivers, cordless angle grinders, and cordless circular saws. The most common voltage used amongst manufacturers (due to its weight, cost, and potential power output) is 18V.
