If the positive lead of a DMM, with the mode set to ohmmeter is connected to the base and the negative lead to the emitter and a high resistance reading is obtained, then what is the type of transistor that is being tested?(a) npn(b) pnp(c) faulty(d) not a transistor, it is a FETI had been asked this question during an interview for a job.This interesting question is from Limits of Operation in chapter BJT Biasing of Analog Circuits

Answer»

Correct answer is (a) NPN

To EXPLAIN I would say: If the POSITIVE lead of a DMM, with the mode set to ohmmeter is connected to the base and the negative lead to the emitter and a low resistance READING is obtained, then what is the type of transistor that is being TESTED is npn.
