Mains electricity by country includes a list of countries and territories with the plugs voltages and frequencies they commonly use for providing electrical power to low voltage appliances equipment and lighting typically found in homes and offices.

How many volts is a wall outlet. An easy way to think of it is the higher the voltage the more power the circuit can deliver. A few appliances like stoves and electric dryers may use 240 volts which require special wiring and outlets. On the other hand if your question is about how much current can. Wall outlets in america have two standard voltage amounts.

For industrial machinery see industrial and multiphase power plugs and sockets some countries have more than one voltage available.

The ones that look like a standard plug with vertical prongs are 120 volt outlets and outlets that fit a plug with diagonal prongs are 240 volt. This is the standard amount but some heavy duty appliances require higher voltages. So for example if r 220 the current will be 1 amp.

Basically as you know ohm law states that v i r. In the united states home wall outlets carry a voltage of 120 vac or voltage from alternating current. Voltage is often described as the pressure of the electricity in a circuit. The standard voltage of a home electrical outlet in the united states is 120 volts although the actual voltage supplied may be as low as 110 volts due to line conditions.

These numbers can fluctuate a little but all low power outlets will measure 110 to 130 volts and high power outlets will measure 200 to 240 volts. Electrical plugs and sockets differ from one another in voltage and current rating shape size and connector type. It depends on the load connected. Plugs and sockets for portable appliances became available in the 1880s to replace connections to light sockets with wall mounted outlets.
