Voltage

The term recognizes italian physicist alessandro volta 1745 1827 inventor of the voltaic pile the forerunner of today s household battery.

Voltage. The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size. The greater the voltage the greater the flow of electrical current that is the quantity of charge carriers that pass a fixed point per unit of time through a conducting or semiconducting medium for a given resistance to the flow. Current is the rate at which charge is flowing. Voltage synonyms voltage pronunciation voltage translation english dictionary definition of voltage.

In brief voltage pressure and it is measured in volts v. It says that the current is equal to the voltage divided by the resistance or i v r. The voltage between the wires is too low to produce a spark. Voltage countable かつ uncountable 複数形 voltages the difference in electrostatic potential between two points in space especially between live and neutral conductors or the earth.

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. Be careful when opening high voltage equipment. Voltage also called electromotive force is a quantitative expression of the potential difference in charge between two points in an electrical field. There is a basic equation in electrical engineering that states how the three terms relate.

Voltage is the difference in charge between two points. It is the push that causes charges to move in a wire or other electrical conductor it can be thought of as the force that pushes the charges but it is not a force voltage can cause charges to move and since moving charges is a current voltage can cause a current. How to use voltage in a sentence. This is known as ohm s law.

Resistance is a material s tendency to resist the flow of charge current. So when we talk about these values we re really describing the movement of charge and thus the behavior of electrons. For industrial machinery see industrial and multiphase power plugs and sockets some countries have more than one voltage available. Voltage definition is electric potential or potential difference expressed in volts.

Voltage electric potential difference electric pressure or electric tension is the difference in electric potential between two points which in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points. 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.
