Why Does Us Use 120V 60Hz Ac?
Once AC was widely accepted as being superior to DC for power generation, transmission and distribution purpose, 120V (110V) became the standard for AC distribution in USA presumably because it used the "safer" voltage level of the DC system. 230V has lower distribution costs and was popularly taken up by Europe.

.

In this regard, why does the US use 120v?

We use 120 volts because Edison chose 110 volts DC for light bulbs. And that was because he couldn't figure out how to create bulbs running on 220 volts without burning out (as /u/Legillo said). So the question really is, why doesn't Europe and the rest of the world use 120v?

Also Know, what does 120v 60hz mean? 120v/60hz means 120 volts 60 hertz frequency as opposed to Europe where they use 240 volts and 50 hertz.

In this regard, why does the US use 60hz?

THE HISTORICAL REASON BEHIND 60Hz SYATEM USED IN USA. The use of 50 versus 60 Hz is purely due to historical reasons, with companies in the US making 60 Hz equipment and those in Europe making 50Hz equipment so that they have a monopoly. Frequencies between 16? Hz and 133? Hz were used on different systems.

Why does US use 110v?

Once AC was widely accepted as being superior to DC for power distribution, 110V became the standard for AC distribution presumably because it used the "safer" Voltage level of the DC system. After metal filament lamps became feasible, 220V became common in Europe because of the lower distribution costs.

Why is American voltage so low?

One reason is that lower voltages tend to be safer, which is why you are receiving 240 volts at the home instead of the thousands of volts generated by the power plant. In terms of power production – all power is the same. The US is at 120 volts, not 110 volts. It was increased sometime around the 1950s.

Is the US AC or DC?

During the early years of electricity, direct current (shorthanded as DC) was the standard in the U.S. But there was one problem. Direct current is not easily converted to higher or lower voltages. Tesla believed that alternating current (or AC) was the solution to this problem.
