Answer:
shorted
Explanation:
A diode is a device that passes current much better in one direction than in the reverse direction.
<h3>Ohmmeter test</h3>
Conceptually, an ohmmeter applies a voltage to the device under test and reports the current through the device on a scale calibrated in ohms. It typically has a low enough open-circuit voltage, and a high enough internal resistance so as to avoid damage to parts under test.
A "continuity" tester may have an open-circuit voltage of a few tens of millivolts and/or a short-circuit current of a few microamps, so as to properly detect continuity and avoid contact damage in "dry" circuits. Such a tester is virtually useless for diode testing.
An ohmmeter suitable for diode testing will generally have an open-circuit voltage of a few volts, and a short-circuit current of a few milliamps. When such a meter is used to test a diode, it will indicate a few kilohms (or less) in the "forward" direction, and several 10s or 100s of megohms in the reverse direction.
<h3>Low-resistance readings</h3>
If the "forward" resistance reading is unusually low (a few ohms), the diode may be <em>damaged</em>. If both forward and reverse readings are unusually low, the diode my be considered to be <em>shorted</em>.
