What Is A Voltage In Electricity
In electrical circuit voltage is the force or pressure that is responsible for pushing the charge in a closed looped conductor.
What is a voltage in electricity. In the international system of units the derived unit for voltage potential difference is named volt. The flowing of charge is called current. If you take a scroll down the page you will notice that most countries have a well defined plug and voltage standard. The greater the voltage the greater will be the current flow through that point.
Transmission lines are used to carry the electricity to a substation. The electricity produced by a generator travels along cables to a transformer which changes electricity from low voltage to high voltage. What is voltage and what does it do. Electricity can be moved long distances more efficiently using high voltage.
Voltage also called electromotive force is a quantitative expression of the potential difference in charge between two points in an electrical field. Residential voltage in the usa and canada is 120 240 volts ac. 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. 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.
When beginning to explore the world of electricity and electronics it is vital to start by understanding the basics of voltage current and resistance. Power enters the dwelling s main electrical panel from a power company transformer as two 120 volt lines with phases that are 180 degrees apart. 120 and 240 volts along with neutral and ground is then distributed to outlet boxes switch receptacle light fixture etc throughout the dwelling. These are the three basic building blocks required to manipulate and utilize electricity.
In brief voltage pressure and it is measured in volts v. In this video we discuss how it work and its purpose to understand how electricity works. The voltage is the electric potential between two points. For industrial machinery see industrial and multiphase power plugs and sockets some countries have more than one voltage available.
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. Many latin american african and asian countries however use a motley collection of. The list also reveals that types a and c are the most frequently used electric plugs worldwide.
