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. [1]: 2 [2]: 622 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 through a wire. In semiconductors they can be electrons or holes. In an electrolyte ... The article explains the concept of electric current , including its definition, unit, formula, and examples. It covers the movement of charge carriers, the role of energy sources in generating current , conventional versus electron flow, and provides solved numerical examples to illustrate calculations related to electric current . Current Electricity Current electricity can be referred to as the flow of electric charge (electrons) through conductors. Electric current (I) is defined as the flow of electric charge. Current electricity is basic for understanding circuits, resistance, power, and other electrical phenomena. 1.0 Basics of Current Electricity Conventional Current Conventional current is the hypothetical flow of positive charge from the positive to negative terminal of a circuit. Factually, it is electrons ... Electric current , any movement of electric charge carriers such as electrons, protons, ions, or holes. Electric current in a wire, where the charge carriers are electrons, is a measure of the quantity of charge passing any point of the wire per unit of time.
