What is the beta of a bipolar junction transistor?
Pick an answer to check it.
Answer: B. The change in collector current with respect to the change in base current
Beta is the current gain of a bipolar transistor: the change in collector current divided by the change in base current. A small base current controls a much larger collector current.
Tip: Beta = Ic / Ib.
