Define current and its unit of measurement.
1 Answer
Current refers to the flow of electric charge through a conductor, such as a wire, in an electrical circuit. It is the rate of flow of electric charges, typically electrons, and is measured in units called amperes, often abbreviated as "A".
The basic unit of measurement for current is the ampere, which is defined as one coulomb of electric charge passing through a conductor in one second. Mathematically, it can be expressed as:
1 Ampere (A) = 1 Coulomb (C) / 1 Second (s)
In practical terms, current describes how many charges pass a point in a circuit per unit of time. It is a fundamental quantity in electricity and plays a crucial role in understanding and designing electrical systems.
