Question

For a transistor the parameter beta = 99. The value of the parameter alpha is

  1. 0.9    
  2. 0.99    
  3. 1    
  4. 9    

The correct answer is: 0.99


    alpha equals fraction numerator beta over denominator 1 plus beta end fraction equals fraction numerator 99 over denominator 1 plus 99 end fraction equals 0.99.
