If electricity was discovered in the states why doesn't the whole world use 110 voltage?

Answer 1

Because the developed world has taken the discovery and improved on it. Power = voltage multplied by current. Higher voltage allows more power per amp. High amps lead to higher losses in transmission cables. Hence the big transmission lines operate at very high voltage to carry power around the country. For a 1kW heater in USA you need to about 9 amps but in UK you only need half that at about 4.5 amps. But after so long with the inefficient 110v system it would be hugely expensive for the USA to change.

Answer 2

It wasn't electricity that was invented in the USA but rather the light bulb. Europeans had plenty of electricity but nothing to use it for. Edison made his bulbs for 110 volts, so people everywhere that used them had to adapt to that "standard" as he had the controlling patent. Keeping the operating voltage low helped keep his DC mains system competitive to AC mains of his competitors.

Answer 3

Electricity was discovered in American lightning, but even Americans don't use hairdryers rated for umpteen zillion volts. Its the distribution system that decides such important issues as AC vs DC and voltage and current flow.
Electrical distribution systems developed differently in different geographic areas.

Answer 4

Beg your pardon, electricity was discovered in the US?

Ancient phonenicans, greeks and parthians knew about it and there was even a battery that dates back to BCE days. Significant development was done by Volta (Italy), Faraday (English), Ampere (French) and Ohm (German). It was Faraday who built the first electromagnetic generator. Where does the USA come into picture?

Answer 5

Electricity was discovered here but there are different currents. Many countries use a direct current which is safer to use than the alternating current that we use here in the states. The alternating current is easier to transmit through the wires.
