Max Collector Current in Transistor Circuits

[Marcin H]

Homework Statement

Calculate the max collector current.

Homework Equations

Ic=BIb
V=IR

The Attempt at a Solution

I'm not sure how to find the max collector current. Don't I need the source voltage to find my Ib and then use that to find my Ic? Is there another way of finding Ic_max? Also, are B,C,D done correctly? I feel like D is wrong because of the huge voltage. (sorry about the bad scan. Had to use phone)

a. it says max POSSIBLE collector current. how high can Vce go?
b. & c. OK
d. can Ic exceed 10V/1K?

Just noticed the 2A error in my calculation for D. Should be 8V for Vce. And for A I'm not sure. I think the max possible collector current would happen in saturation mode. So does that mean Vce=Vce(sat)? So Vce would be 0.2V?

Icmax=(10V-0.2V)/1000ohms = 9.8mA. Never mind. Got it :)
