Question

41. If the current constant for a transistor are a & B then:
(A) aß = 1
(B) B > 1, a < 1​

Answer 1

Answer:

(B) B> 1, A<1

Explanation:

Alpha ( α ) : it is the ratio of collector current variations to emitter current variations. when no load and voltage be constant.

e.g., α = Ic/Ie

where , Ic is collector current variations

Ie is the emitter current variations

similarly,

Beta ( β ) : it is the ratio of collector current variations to base current variations on no load and constant voltage.

e.g., β = Ic/Ib

now, the relationship between alpha and beta

from above relation it is clear that ,

α < 1 and β > 1
