Open Circuit vs. Closed Circuit: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 29, 2023
An open circuit is a broken electrical path, preventing current flow; a closed circuit is a complete path, allowing current to flow.

Key Differences

In an open circuit, the electrical path is interrupted, halting the flow of current. Conversely, a closed circuit offers an unbroken path, allowing electricity to circulate.

Open circuits are often the result of breaks or gaps in wiring or components. In contrast, closed circuits are characterized by continuous, connected paths that facilitate electrical flow.
