For the saturation operating mode of an npn bipolar transistor (common base), the B-E junction and B-C junction are ________ and ___________ biased, respectively.

A. forward; forward
B. forward; reverse
C. reverse; forward
D. reverse; reverse

Distribution of minority carriers in the base region is exactly linear. ()

In reverse-active, the gradient in the minority carrier electron concentration in the base is in the opposite direction compared with the forward-active mode, so the emitter and collector currents will change direction. ()

We are interested in calculating currents in the bipolar transistor that, as in the simple pn junction, are determined by the diffusion of ________.

A. minority carrier
B. majority carrier
C. both carriers
D. either minority or majority carrier
