Question

A diode is tested with an ohmmeter. The ohmmeter indicates a reading of 4  $\Omega$ regardless of which way the ohmmeter leads are connected. The diode is probably ____.

Quizplus · Accepted Answer

A diode should show low resistance in one direction and high resistance in the opposite direction. A reading of zero ohms (or very low resistance) in both directions suggests the diode is shorted, allowing current to flow freely in both directions.
