Question A-002-003-001

What is the beta of a bipolar transistor?

Correct Answer

The change of collector current with respect to base current

Explanation

Beta (β) or hFE of a bipolar junction transistor (BJT) is the ratio of the change in collector current (ΔIc) to the change in base current (ΔIb) in common-emitter configuration (β = ΔIc / ΔIb).
