What do we call a system that provides a complete path for the flow of electricity?

A system that provides a complete path for the flow of electricity is known as a circuit. This is because a circuit consists of various electrical components such as resistors, capacitors, inductors, and power sources connected in such a way that electricity can flow uninterrupted from one point to another. When a circuit is closed, it allows electrons to move freely, fulfilling the essential condition for current to flow efficiently.

While a network can refer to an interconnected group of components or systems, it does not specifically denote the complete path needed for electricity to travel. Similarly, a grid is usually used in a broader context to describe a large-scale network of interconnected electrical distribution systems, not just the simple pathway for electric current. Lastly, a connection implies a link between components but does not necessarily indicate that a true circuit is formed unless it includes a full loop for current to flow.
