1.	A silicon semiconductor diode when subjected to ohmmeter testing gives high resistance in both directions. Which of the following is the correct inference to be drawn?(a) Diode is faulty(b) Power failure to the Ohmmeter(c) Diode is short-circuited(d) Diode is open circuitedThe question was asked in an interview for internship.The query is from Types of Diode and their Testing in chapter Diode Circuit of Analog Circuits
Answer» The correct choice is (a) Diode is faulty The best EXPLANATION: A proper diode gives a low resistance READING along one direction and high resistance reading along the other. HENCE, if diode gives high resistance READINGS in both directions, then the diode MUST be faulty.
