In the United States, home wall outlets carry a voltage of 120 VAC, or voltage from alternating current. This is the standard amount, but some heavy-duty appliances require higher voltages.Know More
Most stoves, washers and dryers have heavier power requirements and run on a 240 VAC outlet that requires its own circuit.
The United States is one of the few countries still operating on 120 VAC outlets. Many countries in the European Union have switched to 240 VAC for their standard outlets. Some countries use less; Japan makes use of 100 VAC outlets. When traveling to another country, make sure to carry voltage adapters to avoid damage to appliances.Learn more about Electrical
The standard mains voltage used in the United States is approximately 110 to 120 volts, according to Georgia State University's physics department. Depending on the power load, it can vary between these two measurements.Full Answer >
Thirty-amp fuses can handle both 120 and 240 volts, which are the common voltages in the United States. Fuses or circuit breakers prevent too much current going through a circuit and reduce the risk of fire.Full Answer >
A multimeter is able to let you know how much electricity is flowing through a wall outlet. Though it generally is not a good idea to insert objects into a wall outlet, a multimeter only works when you insert its probes into an outlet. There is a safe way to do this.Full Answer >
