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. The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor. In electric circuits the charge carriers are often electrons moving thr. Common symbolsISI unitSymbolThe 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 . The conventional direction of current, also known as conventional current, is arbitrarily defined as the direction in which positive charges flow. In a, the moving charged particles that constitute the electric curr. . Ohm's law states that the current through a conductor between two points is directly to the across the two points. Introducing the constant of proportionality, the, one arrives at the usua. . In (AC) systems, the movement of periodically reverses direction.
