How about "volts"? I don't think "amperes" is what you had in mind.

Here in America, we are resistant to change; period!

We are the only large country that has not embraced the metric system. The entire world uses 50 Hz 220 Volt power except for in the USA and a few other places.

The difference in voltage between Europe (220 volts) and North America (120 volts) is a result of historical standards that were established before the modern electrical grids we have today. The higher voltage used in Europe allows for more efficient transmission of electricity over longer distances, while the lower voltage in North America is a compromise between safety concerns and efficiency. The amperage capacity of a system is based on the voltage and the power requirements of the devices being used.

How many amps does a 900 watt microwave oven use?

It won't run a microwave at all. Microwaves require an a.c. supply of 230 V (Europe) or 120 V (N America).


What voltage is the kettle?

It depends where you bought it. In North America, its rated voltage will be 120 V whereas, in Europe, its rated voltage will be 230 V.


What is the amperage of the European electrical power systems versus that of North America?

In Europe, 230 V is the normal domestic supply whereas in the US it is 120 V. For an appliance of a certain power rating, the current taken will be inversely related to the voltage, by Ohm's Law, ie power = volts x amps. So the current at 230 V will be in the ratio 120/230 of that taken at 120 V


How many volts does a North American outlet generates?

In Canada and the United States, wall outlet voltage is standardized at 110 to 120 volts (anywhere in that range is considered "OK"). In Europe - most of the rest of the world, actually - it is standardized at 220 volts.

Are 100 watt bulbs designed to be use on 250 volt supply?

250 V is not a nominal voltage used in Europe or in North America, although it may be elsewhere in the world. If so, then, yes, there will be 100-W lamps marketed for that particular voltage in that particular part of the world.The nominal voltage in Europe is 230 V and the nominal voltage (for lamps) in North America is 120 V. So, in Europe and North America, 100-W lamps are rated at 230 V and 120 V respectively.


What continent is at 60 degree north and 120 degree west?

North America is at 60 degrees north and 120 degrees west.


What does 1500 watts equal in amps at 120 volts?

To convert watts to amps at 120 volts, use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the calculation would be: 1500 watts / 120 volts = 12.5 amps.
