In a common base transistor circuit, the current gain is 0.98 . On changing the emitter current by 5.00 m A , the change in collector current is
Options
- A0.196 m A
- B2.45 m A
- C4.9 m A
- D5.1 m A
Correct answer
C. 4.9 m A
Step-by-step solution
Given, α = 0.98 ∴ α = ∆ I c ∆ I e 0.98 = ∆ I c 5 ⇒ ∆ I c = 4.9 m A
