What is defined as the flow of electrons through a conductor?

The flow of electrons through a conductor is defined as current. This concept is fundamental in understanding electrical systems and circuits. Current refers to the movement of charged particles, primarily electrons, which are facilitated by a difference in electrical potential (voltage) across a conductor. When a voltage is applied to a conductor, it causes electrons to move, creating a flow of electric charge, which is what we refer to as current.

To provide some context, voltage represents the electrical potential difference that drives the current through the conductor, while resistance is the property of the conductor that opposes this flow of electrons. A circuit is a closed loop that allows the flow of current; however, it does not define the flow itself. Understanding these distinctions is crucial for anyone studying electrical systems and building maintenance, as they’re foundational concepts in the operation of electrical circuits.
