        ELECTRIC CURRENT   small summary Electric current definition: An electric current may be a flow of electrical charge during a circuit. More specifically, the electrical current is that the rate of charge flow past a given point in an electrical circuit. The charge are often charged electrons or charge carriers including protons, positive ions or holes. The magnitude of the electrical current is measured in coulombs per second, the common unit for this being the Ampere or amp which is designated by the letter ‘A’. The Ampere or amp is widely used within electrical and electronic technology along side the multipliers like milliamp (0.001A), microamp (0.000001A), then forth. Current flow during a circuit is generally designated by the letter ‘I’, and this letter is employed in equations like Ohms law where V=I⋅R. What is electric current: the fundamentals The basic concept of current is that it's the movement of electrons within a substance. Electr...
