What does an open circuit indicate?

An open circuit indicates that there is a break in the path that current follows, meaning that current cannot flow through the circuit. This typically occurs when a component is removed, a switch is open, or there is a break in the wiring. This condition prevents the circuit from completing its path, which is essential for current to flow. As a result, no electrical devices or components connected within that circuit can operate until the circuit is closed, allowing current flow once again. Understanding this concept is crucial for troubleshooting electrical systems, as identifying an open circuit can lead to resolving issues with non-functional electrical devices or systems.
