For a transistor, α d c and β d c are the current ratios, then the value of β d c - α d c α d c ⋅ β d c is

Options

  1. A1
  2. B1.5
  3. C2
  4. D2.5

Correct answer

A. 1

Step-by-step solution

β d c = α d c 1 - α d c ⇒ 1 - α d c = α d c β d c β d c - α d c α d c ⋅ β d c = β d c 1 - α d c β d c α d c ⋅ β d c = 1 - α d c β d c α d c = 1 - 1 - α d c α d c = 1 - 1 + α d c α d c = 1
