2.1: Ohm’s Law - How Voltage, Current, and Resistance Relate
The SI unit of electric current is the ampere, or amp, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit.: 15 Electric current is measured using a device called an ammeter.: 788 See more An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. … See more The conventional direction of current, also known as conventional current, is arbitrarily defined as the direction in which positive charges … See more In alternating current (AC) systems, the movement of electric charge periodically reverses direction. AC is the form of electric power most commonly delivered to businesses and … See more Natural observable examples of electric current include lightning, static electric discharge, and the solar wind, the source of the polar auroras. Man-made occurrences of electric current include the flow of conduction electrons in metal wires such as … See more The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity). Current intensity is often referred to simply as current. The I symbol was used by André-Marie Ampère, after whom the unit of electric current is … See more Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that … See more Current can be measured using an ammeter. Electric current can be directly measured with a See more WebElectric current is a scalar quantity. S. unit of electric current is coulomb/second or ampere.
