In a transistor amplifier, AC current gain is 64, the load resistance is 5400 Ω and the input resistance of the transistor is 540 Ω. The voltage gain is (a) 540 (b) 600 (c) 640 (d) 6400

Answer: (c). AV = β(RL)/(Ri) AV = 64 × (5400)/(540) = 64 × 10 = 640 So the answer is (c) 640.

Junction Transistor

In a transistor amplifier, AC current gain is 64, the load resistance is $5400\ \Omega$ and the input resistance of the transistor is $540\ \Omega$ . The voltage gain is

Show answer and solution

Answer: (c)

$A_V = \beta\frac{R_L}{R_i}$
$A_V = 64 \times \frac{5400}{540} = 64 \times 10 = 640$
So the answer is (c) 640.
