What is the resistance reading of an open wire?

An open wire condition occurs when there is a break or disconnection in the conductor that prevents electrical current from flowing. In this scenario, the resistance is measured between two points along the wire, and since there is no continuous path for current to travel, the resistance effectively becomes infinite. This means the wire is essentially non-conductive at that point, leading to an infinite resistance reading.

In circuits, infinite resistance is representative of an open circuit; in such cases, no current can flow and, as a result, it reflects the concept of a break or discontinuity in the conductive path. This principle is crucial in troubleshooting and maintenance, as identifying an open circuit helps in diagnosing issues promptly.

The other answer choices reflect specific resistive values of conductors that are intact and allowing current to flow, which doesn't apply to an open wire scenario.
