A transistor having a equal to 80 has a change in base current of 250 A , then the change in collector current is

Options

  1. A20,000 ~mA
  2. B200 ~mA
  3. C2000 ~mA
  4. D20 ~mA

Correct answer

D. 20 ~mA

Step-by-step solution

= ( i_C i_B )80= i_C 250 10⁻⁶ i_C=80 250 10⁻⁶ i_C=20000 10⁻⁶=20 10⁻³=20 ~mA
