#### Ryan$Joined Dec 14, 2018 178 Hi guys, May I get a help how does exactly "one point of voltage=value of voltage" could interpreted as mode operation is cutoff and in the same time as Forward Active? I mean How exactly two cases is applied at "one point" ... it sounds for me as a magic or miracle at one point having more than one mode of operations of transistor May anyone please elaborate or gimme analogues how exactly one point could lead the transistor over it to work as "many mode of operations "? in general one point(one voltage value) could be interpreted to "one" mode operation that could transistor work over it.

For example, at the edge of cutoff region and Forward Active region, the current over that point (that edge) is zero although we are on region Forward Active but we also on region Cutoff, so how can I decide what's the current over that common point?!

I don't understand what you are saying. Go ask your professor.
