CBSE · Class 10 · Science · ElectricityWhat is electric current? Define it and state its SI unit.

Electric current is fundamentally defined as the rate of flow of electric charge through a specific cross-section of a conductor. When electrons move in a directed manner through a conductor, they constitute an electric current. Mathematically, it is expressed as the quantity of charge passing per unit of time, where I equals Q divided by t. The standard International System of Units (SI unit) for measuring electric current is the ampere, which is named in honor of the celebrated French physicist André-Marie Ampère. One ampere of current is specifically defined as the flow of one coulomb of electric charge passing through any given cross-section of a conductor in exactly one second of time.
