What are the three requirements for current to flow through a conductor?

The selection of the requirement involving a source of current, a conductor, and voltage to push current accurately captures the fundamental principles necessary for current to flow through a conductor.

In electrical theory, a current requires a complete circuit that incorporates these essential components. A source of current, such as a battery or generator, provides the electrical energy needed to create movement of charge. The conductor, typically a wire, serves as the pathway allowing that current to flow. Finally, voltage acts as the driving force that motivates the electrons to move through the conductor, facilitating the flow of current.

The combination of these elements ensures that an electrical circuit is functional, allowing for safe usage of electric power in various applications, including healthcare settings. Understanding this is crucial for compliance with safety protocols and avoiding electrocution hazards.
