Multiple choice

The current gain (β) of a transistor in common emitter mode is 10. If the change in collector current is by 50mA at constant VCE, the necessary change in the base current is

  1. 0.5mA

  2. 5mA

  3. 50mA

  4. 5A

  5. 8A

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

By definition , β = (∆IC / ∆IB) at constant VCE, therefore , ∆IB = ∆IC / β = 50/10 = 5mA.
