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

When pn junction is forward biased resistance is low. When pn junction reverse biased resistance is high. Because of this reason, we can amplify currents. For this reason, Transistors can be used as:- An amplifier A switch Logic gates
