If an ohmmeter is connected across an inductor and the pointer reads zero ohms, the inductor is:

Explanation:
An ohmmeter measures resistance by pushing a small current through a component and watching the voltage drop. A reading of zero ohms means there is a direct electrical path with essentially no resistance—a short circuit. For an inductor, that indicates the coil is bypassed or the winding is damaged so it presents almost no resistance at DC. If it were open, you would see no continuity (infinite resistance). If it were active or not connected, the meter wouldn’t read a valid winding resistance. So, a zero-ohm reading across the inductor points to a shorted condition.
