List of top Electronics and Communication Engineering Questions on Transistors asked in CUET (PG)

Arrange the following BJT circuits in decreasing order of input resistance: 
A. Common base 
B. Common emitter 
C. Emitter follower 
D. Emitter follower using Darlington pair

Consider the following fixed bias circuit configuration. Find $I_C$ ($\beta = 50$, $V_{BE} = 0.7V$).

Assertion (A): FET is a majority carrier device whereas BJT works based on movement of both majority and minority carriers. Reason (R): Thermal runaway occurs in FET circuits but does not occur in BJT circuits.
