In a transistor if I_C I_E = and I_C I_B = . If varies between 20 21 and 100 101 , then the value of lies between

Options

  1. A1-10
  2. B0.95-0.99
  3. C20-100
  4. D200-300

Correct answer

C. 20-100

Step-by-step solution

= 1- ₁= 20 21 1- 20 21 =20, ₂= 100 101 1- 100 101 =100 The value of lies between 20-100 .
