A diode on being checked by a DDM with diode checking function results

1.	A diode on being checked by a DDM with diode checking function results in an open loop indication in both directions. Which of the following is the correct inference drawn from the given situation?(a) Power failure to the DDM(b) Diode is faulty(c) Diode is proper(d) Device isn’t connected properlyI got this question in an online interview.The origin of the question is Types of Diode and their Testing topic in portion Diode Circuit of Analog Circuits
Answer» The correct answer is (b) Diode is faulty To ELABORATE: A diode allows electrical conduction in just one DIRECTION. Hence, if an instrument shows an open loop INDICATION in both the directions, then the diode is faulty.
