JEE Main 2022 — Semiconductors Question with Solution

JEE Main 2022 (26 Jul Shift 2)

Question

The typical transfer characteristic of a transistor in CE configuration is shown in figure. A load resistor of 2 kΩ is connected in the collector branch of the circuit used. The input resistance of the transistor is 0.50 kΩ. The voltage gain of the transistor is

Correct answer
200

Step-by-step explanation

The current gain in C-E configuration is given by,

⇒β=ΔICΔIB

RC=2 kΩ, RB=0.50 kΩ

Now the voltage gain =ΔICRCΔIBRB=5×10-3100×10-6×20.5

=10-25×10-5=10005=200
