## Why does US use 120v 60hz AC?

company was distributing DC electricity at 110 volts in the United States.

…

Meanwhile, the German company AEG started generating electricity and became a virtual monopoly in Europe.

They decided to use 50Hz instead of 60Hz to better fit their metric standards, but they stayed with 120V..

## Which is better 50hz or 60hz?

50Hz vs 60Hz in operating speed The primary difference between 50 Hz (Hertz) and 60 Hz (Hertz) is, well, 60Hz is 20% higher in frequency. … Lower the frequency will be the iron losses and eddy current losses. Lower the frequency, speed of induction motor and generator will be lower.

## Can I connect 120v to 220v?

Do not plug a 120V device directly into a 220V wall socket, even if the plug shape and size are identical. Although goods sold in the U.S. but available around the world sometimes accommodate 220V voltages — iPods, for example — other devices can be destroyed by such high voltages.

## How many watts is a 120v 60hz light bulb?

The light bulb can be of any wattage based output in Lumens. So say 120 Volts x 20 amps, is 2,400 Watts.

## How many watts is 3 amps?

## Will 60hz work on 50hz?

Can a 60Hz motor run on 50Hz power supply? For a generic answer: yes you can, IF: you reduce the voltage by 50/60, the equipment doesn’t care, you don’t care about potentially overheating the motor, the process/load can tolerate the lower speed/torque, etc.

## Is 220v more dangerous than 110v?

220v wiring uses less current than 110v wiring. Power is measured in watts. … Although it’s true that 220v requires less current to provide the same amount of power, it can still carry much more current and poses a higher risk of serious.

## How does a 120v AC work?

Like DC power, AC requires a potential difference to do work. For 120V plugs with two wires, the difference is between a hot wire (connected to the electrical source), and a neutral wire (connected to the electrical source and to the earth). … The neutral wire is the current return path for 120V circuits.

## What is the difference between 110v and 120v?

You’ll often hear voltages in your home referred to as 110V, 115V, or 120V. This can be confusing but the bottom line is they are referring to the exact same thing. 120V is the AC voltage on a single hot wire in your home with respect to neutral (or ground).

## What does 120v AC mean?

The household electricity our North American appliances use is delivered at 120VAC (volts alternating current) 60 Hz. … When the electric current flows it rises from 0 volts to 120 volts back to 0 volts and then it falls to negative 120 volts and rises back to 0 volts. This rise and fall completes one cycle (1 Hz.)

## Is 60hz more dangerous than 50hz?

The current flowing through a high resistance such as the human body is therefore about twice the number of milliAmps at 230 Volts than at 115 Volts. … This dependence on current strength which, in its turn is determined by the voltage available makes 230 Volt lines at 50 Hz more dangerous than 120 Volts at 60 Hz.

## Is 120v AC or DC?

It’s AC, specifically at 240VAC or 120VAC depending on which country you live. AC is normally preferred to DC for domestic use because: 1. Easier to step up or down according to your application compared to DC (It’s common to have loads or actuators using 240V, 120V, 48V, 24V, or 12VAC.

## 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. 14 watts is 14 watts. If you used it for an hour it would be 14 watt hours or . 014 kWh which is what you see on your power bill. The value printed on a device is an appoximate.

## Why is AC power 60 Hz?

Although 50 Hz was suitable for both, in 1890 Westinghouse considered that existing arc-lighting equipment operated slightly better on 60 Hz, and so that frequency was chosen.

## What wattage is 120v 60hz?

120v/60hz means 120 volts 60 hertz frequency as opposed to Europe where they use 240 volts and 50 hertz. 14 watts is 14 watts. If you used it for an hour it would be 14 watt hours or . 014 kWh which is what you see on your power bill.

## What wattage is 120v?

Then, since you have 120V, you can figure the watts. P = IE, 1 Amp x 120V = 120 Watts. There is no way to convert 120 volts to watt as watt represents power and is equal to the product of voltage and current.

## How many watts is 220 volts?

A 220 volt AC power line supplies current and the resulting power is according to the formula P = current x volts. So if you connect a motor that uses 10 amps you are consuming 220 x 10 = 2200 watts.
