flow of electrical charge or movement of charged particles from point to point
Define current.
The flow of electrical charge or movement of charged particles from point to point is called electric current. Electric current is characterized by the movement of electrons, which are negatively charged particles, through a conductor.
The flow of electrons requires a closed circuit, which is formed by connecting the source of electrical energy, such as a battery, to a conductor, such as a wire. Once the circuit is completed, the electric current flows from the negative terminal of the battery, through the conductor, and back to the positive terminal of the battery.
The rate at which electric charge moves through a conductor is measured in amperes (A), and is equal to the amount of charge passing through a point in the conductor per unit time. Electric current is affected by several factors, such as the voltage of the electrical source, the resistance of the conductor, and the length and cross-sectional area of the conductor.
Therefore, the flow of electrical charge or movement of charged particles from point to point is an important concept in understanding the behavior and applications of electricity.
