What fault is indicated by an open inductor?

An open inductor is characterized by a break in its winding, which disrupts the flow of electrical current through the component. This condition results in no continuity between the leads of the inductor.

When an inductor is functioning properly, it allows current to flow and stores energy in its magnetic field. However, if there is an open circuit condition—typically caused by a break in the wire or an internal failure—the electrical path is effectively interrupted. As such, a multimeter would show infinite resistance or no continuity when tested between the leads, confirming the open condition.

Understanding this behavior is crucial for troubleshooting in aircraft electronics. An open inductor not only fails to perform its intended function but can also impact the stability and performance of the entire circuit in which it is integrated.
