- Electric current - Wikipedia
An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space It is defined as the net rate of flow of electric charge through a surface
- Electricity - Wikipedia
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations
- Electric current - Simple English Wikipedia, the free encyclopedia
An electric current is a flow of electric charge through a conductor The equation of current is: [1] The SI unit of electric current is the ampere (A) This is equal to one coulomb of charge in one second Electric current can be found in wires, batteries, and lightning
- Ampere - Wikipedia
The ampere ( ˈæmpɛər ⓘ AM-pair, US: ˈæmpɪər ⓘ AM-peer; [1][2][3] symbol: A), [4] often shortened to amp, [5] is the unit of electric current in the International System of Units (SI)
- Alternating current - Wikipedia
Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction
- Direct current - Wikipedia
Direct current (DC) is one-directional flow of electric charge An electrochemical cell is a prime example of DC power Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams
- Electric current | Formula Definition | Britannica
Electric current, any movement of electric charge carriers such as electrons, protons, ions, or holes Electric current in a wire, where the charge carriers are electrons, is a measure of the quantity of charge passing any point of the wire per unit of time
- Current density - Wikipedia
In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section [1] The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at
