What is the flow of electrons through a material called?

The flow of electrons through a material is defined as current. In electrical terms, current refers specifically to the movement of electric charge, which in most cases is the flow of electrons in a conductor. This movement is measured in amperes (A), which quantifies how much charge passes through a point in a circuit over a specific period. Understanding current is essential for comprehending how electrical systems operate, as it directly affects the functionality of circuits and devices.

The other concepts relate to different aspects of electrical circuits. Voltage refers to the potential difference that drives current through a circuit, while resistance measures how much a material opposes the flow of current. Power is the rate at which electrical energy is transferred or converted and is calculated as the product of voltage and current. While all of these terms are interconnected in the field of electricity, it is current that specifically describes the flow of electrons.
