What is defined as a flow of electricity through a conductor?

The concept of a flow of electricity through a conductor is specifically defined as current. Current refers to the movement of electric charge, typically measured in amperes (A). In most electrical circuits, this charge consists of electrons flowing through a conductor, such as a wire.

Current is essential for powering devices and performing work in an electrical circuit. The flow is driven by a potential difference, known as voltage, but it is the current that actually represents the movement or flow of electricity. This is a foundational concept in electrical engineering and physics, as understanding current is crucial for analyzing how circuits operate and how electricity is utilized in various applications.

Voltage, while closely related, refers to the potential energy per unit charge and acts as the driving force behind the current but does not itself define the flow. Resistance is a measure of how much a material opposes the flow of current, while induction is a phenomenon related to the production of voltage across a conductor due to a changing magnetic field, rather than the flow of electricity itself.
