In a C E transistor amplifier, the signal voltage across the collector resistance is 2.5 ~V . The input signal voltage is 0.02 ~V . If the base and collector resistances are 1.5 k and 2.5 k , then the current amplification factor is

Options

  1. A100
  2. B50
  3. C75
  4. D125

Correct answer

C. 75

Step-by-step solution

We know that A_v= R₀ R_i , A_v= Voltage amplification factor aligned & 2.5 0.02 = 2.5 1.5 & = 1.5 0.02 =75 aligned
