JEE Main 2016 — Semiconductors Question with Solution
JEE Main 2016 (09 Apr Online)
Question
An unknown transistor needs to be identified as a or 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 transistor?
Choose an option
Show full solutionCorrect option: B
Correct answer
B+ve terminal 2, -ve terminal 1, resistance high
Step-by-step explanation
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
