If ( )-current gain of a transistor is ( 0.98 . ) What is the value of ( )-current gain of the transistor ?

Options

  1. A( 0.49 )
  2. B(19
  3. C( 4.9 )
  4. D( 55 )

Correct answer

B. (19

Step-by-step solution

For a transistor, ( )-current gain and ( )-current gain are related as [ = 1- ] Given, ( )-current gain ( =0.98 ) Therefore, ( = 0.98 1-0.98 = 0.98 0.02 =49 ) ( )-current gain of transistor is ( 49 ).
