Question

An unknown transistor needs to be identified as a n-p-n or p-n-p type. A multimeter, with +ve and -ve terminals, is used to measure resistance between different terminals of transistor. If terminal 2 is the base of the transistor then which of the following is correct for a p-n-p transistor?

Quantrex Academy · Accepted Answer

Correct answer: B. +ve terminal 2 , -ve terminal 1 , resistance high

p-n-p transistor : Positive at terminal 2 and negative at terminal 1 implies p-n junction is reverse biased and hence offers high resistance.
