An electrical charge traveling through a conductor is called an electric current. This flow of electric charge is typically carried by electrons, which move through the material due to the presence of an electric field. The amount of current flowing through a conductor is measured in amperes (A), and it depends on the voltage applied to the conductor and the resistance of the material. Conductors with low resistance allow current to flow easily, while those with high resistance impede the flow of current. Electric currents have many practical applications, from powering electronic devices to running motors and generating electric fields.
