Us Electric Current Voltage

Current is the rate at which electric charge flows past a point in a circuit.

Us electric current voltage. If you take a scroll down the page you will notice that most countries have a well defined plug and voltage standard. 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. It is the form of electrical power that is delivered to homes and businesses and it is the form of electrical power that consumers. Many latin american african and asian countries however use a motley collection of often incompatible plugs and sometimes also the voltage differs from region to region.

In brief voltage pressure and it is measured in volts v. At the time the us also wanted to change but because of the cost involved to replace all electric appliances they decided not to. Voltage is the electrical force that would drive an electric current between two points. The term recognizes italian physicist alessandro volta 1745 1827 inventor of the voltaic pile the forerunner of today s household battery.

Thick wires carry the electric current from the generator to a transformer which increases the voltage of the electric current to 500 000 volts or more before electricity can be sent to the power grid. Originally europe was 120 v too just like japan and the us today but it was deemed necessary to increase voltage to get more power with fewer losses and less voltage drop from the same copper wire diameter. For industrial machinery see industrial and multiphase power plugs and sockets some countries have more than one voltage available. When beginning to explore the world of electricity and electronics it is vital to start by understanding the basics of voltage current and resistance.

A few appliances like stoves and electric dryers may use 240 volts which require special wiring and outlets. To see if a voltage converter is needed look at the informational panel on the back of the electrical device in question. Voltage is the pressure from an electrical circuit s power source that pushes charged electrons current through a conducting loop enabling them to do work such as illuminating a light. In some parts of canada it is known as hydro is the general purpose alternating current ac electric power supply.

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. At first these concepts can be difficult to understand because we cannot see them. High voltage lines carry the current to substations on the power grid. Mains electricity as it is known in the uk and some parts of canada.

Transformer increases power voltage. Us terms include utility power power grid domestic power and wall power.
