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

Options

  1. A200
  2. B250
  3. C300
  4. D150

Correct answer

A. 200

Step-by-step solution

The current gain in C-E configuration is given by, ⇒ β = Δ I C Δ I B R C = 2 kΩ , R B = 0 . 50 kΩ Now the voltage gain = Δ I C R C Δ I B R B = 5 × 10 - 3 100 × 10 - 6 × 2 0 . 5 = 10 - 2 5 × 10 - 5 = 1000 5 = 200
