Question

19, A bipolar junction transistor BJT that has collector current Ic of 100mA and base current of 0.5mA will have dc

current gain Beta of?


(A) 20
(B) 100
(C) 200
(D) 400

Answer 1

200

Step-by-step explanation:

To determine the DC current gain (β) of a bipolar junction transistor (BJT), we can use the formula:

β = Ic / Ib

Given that the collector current (Ic) is 100mA and the base current (Ib) is 0.5mA, we can substitute these values into the formula:

β = 100mA / 0.5mA

Simplifying the expression:

β = 200

Therefore, the DC current gain (β) of the BJT is 200.

The correct option is (C) 200.
