Question

the maximum value of collector current in a biased transistor is
select one:
○ a. greater than ie
○ b. ic(sat)
○ c. less than ib
○ d. βdc*ib

Explanation:

In a biased transistor, when it is in saturation mode, the collector current reaches its maximum value, denoted as \(I_{C(sat)}\). The emitter current \(I_E=I_B + I_C\), so \(I_C\) can't be greater than \(I_E\). Also, \(I_C=\beta_{DC}I_B\) is the relationship in the active mode, not the maximum value. And \(I_C\) is much larger than \(I_B\) (not less) in normal transistor operation.

Answer:

B. \(I_{C(sat)}\)
