# Circle vs. Circuit: What's the Difference?

Edited by Harlon Moss || By Janet White || Updated on November 29, 2023

**A circle is a simple geometric shape with all points equidistant from a center, whereas a circuit is a path or loop through which electric current flows or a series of events.**

## Key Differences

A circle is a basic geometric figure, flat, and round, with every point on its edge equidistant from its center. In contrast, a circuit refers to a complete and closed path, typically for electrical currents, or a sequence of actions or events forming a loop.

In mathematics, a circle is defined purely by its geometric properties and does not imply movement or flow. A circuit, however, especially in electronics, implies a dynamic flow of electricity or the movement of something along a closed loop.

Circles are often used symbolically to represent unity, infinity, or wholeness due to their continuous, unbroken shape. Circuits are associated with connectivity, energy flow, and cyclical processes, especially in technology and event sequences.

The concept of a circle is universally understood in geometry and is a fundamental shape in various fields, including art and design. The idea of a circuit, while also prevalent, is more commonly associated with specific fields like electronics, motorsports, or systematic processes.

When drawing, a circle is a simple curve, whereas a circuit, when represented, often includes multiple components like wires, resistors, and other electronic elements, or can depict a series of stages in a process.
