The USA uses a power supplyt voltage of 110 to 120 volts. It is foreign to people who are outside the USA. The lower voltage is held to be safer in the home.

Why 220v in the Phil and 110v to the other country?

i think the answer is more on economical reasons ( 220v in the phil ).. since Voltage is inversely proportional to current..the higher the voltage, the lower the current..the lower the current, the smaller the electrical cable to use. In short, if we used 220v, electrical cable to be used is much smaller compared to the cable used in 110v..Smaller cable means less price than of the much larger cable.. :))


Use foreign in a sentence?

That person is from a foreign country.


Can you use a lamp used for a 220 V country in a 110v country by just changing the bulb?

Yes. You also will need an adapter for the plug, so it fits in the electrical socket.

How many watts is 20A at 110v?

To calculate the watts from amperes and volts, you can use the formula: Watts = Amperes × Volts. For 20A at 110V, the calculation would be 20A × 110V = 2200 watts. Therefore, 20A at 110V is equal to 2200 watts.


Can you use a foreign quarter in the US?

NO, but can exchange at current rate for US.


How you can use your 110v arc welder on 220v country?

You will need a 'step up transformer' but it is important to provide the details on the information panel of the welder before ordering


How do you get a 110V outlet in a car?

You will need to purchase a power inverter. An inverter changes direct current, like what is in your car, to alternating current, like in a home. You will need to know the wattage of the item you are powering in order to buy the correct sized invertor.


Can I use a prescription from another country to obtain medication in my current location"?

No, you cannot use a prescription from another country to obtain medication in your current location.


Can you get 110v from 415v?

Yes, you can step down 415V to 110V using a transformer. The transformer will reduce the voltage to the desired level, allowing you to power devices that require 110V. Be sure to use a transformer rated for the appropriate voltage conversion.


Can you use a French socket in Denmark?

There are two facets to this question: Can it be used safely, and can it be used legally. This applies to foreign fixtures in any country. This is a matter of the rating on the components. You cannot exceede the voltage capacity of the outlet or it will arc internally. The voltage of the circuit feeding the outlet must be the same as the voltage the outlet is designed for. You can use a 220V US NEMA outlet on European 220V safely, but you can't use a US 110V outlet. Also, the overcurrent device on the circuit must be less than or equal to the maximum current rating on the fixture. A 10A or 15A breaker is okay for a 110V 15A US outlet, a 20A breaker is not. If you respect the voltage rating and insure the current rating will not be exceeded, the fixture should be safe. This is another matter entirely. It is a matter of wether or not whatever regulating body that certified the outlet is recognized in your country. You will need to contact your local building inspector / code inforcement person to find out for sure. I wouldn't get my hopes up.


What causes a 220v wire to pull only 110v?

The fact that it's supposed to. Voltage is stated as the difference between the two wires carrying electricity to the load. When they bring power to the house from the utility, you get two wires carrying 110v but they're 180 degrees out of phase. Imagine one carries positive 110v and the other carries negative 110v. If you hook one of these wires plus a neutral (zero volts) to the load, you get 110v--110v over 0v. If you hook both of them to the load, you get positive 110v over negative 110v, or 220v. So...red to white is 110v, black to white is 110v, red to black is 220v.
