why 120 volts

The standard electric outlet you'll plug a lamp or vacuum into is a 120V outlet.
When you plug in your oven or washing machine, though, you'll notice that an appliance outlet has a different appearance than a standard outlet.
That's because a large appliance requires a 240V outlet.

Why is US 110v and Europe 220v?

Companies in Europe realized that supplying power at 220 volts instead of 110 volts would be cheaper.
At a higher voltage, electric companies can deliver the same power with less current – picture a narrow stream flowing quickly compared to a wider stream flowing slowly.
And less current allows for thinner wires.

Why usa uses 120 volts and not 220 volts?

Historically speaking, one of the main reasons why the US retained 120V as its standard power supply was due to the power grid already being largely established, making it too costly to switch over.
The main benefits of 120V power are quite limited.

Why was 120 volts chosen?

Now, historically speaking, one of the main reasons why the US stuck with 120V as its standard power supply largely has to do with the fact that it was initially tied to carbon filament lighting._{30 sept. 2016}
