1.	What is the expected reading obtained on a Digital Display Meter with diode-checking function when a proper functioning silicon semiconductor diode is connected across its leads in the forward bias configuration?(a) 0.67 V(b) 0.3 V(c) Open Loop Indication(d) Varies with the diodeThe question was asked in a job interview.The above asked question is from Types of Diode and their Testing in portion Diode Circuit of Analog Circuits
Answer» CORRECT choice is (a) 0.67 V The best I can explain: The diode checking FUNCTION on the METER when used causes a current of 2 mA to flow through the diode and hence under forward bias, the voltage is determined to be 0.67 V. Germanium diodes show a drop AROUND 0.3V.
