When Ic=saturation Vce=0V. By applying KVL in the right side, we can get;

Vcc-IcRc-Vce-IeRe=0
Where, Vce=0V and Ic=Ie.
Therefore;
Vcc-Ic(Rc+Re)=0.
Ic=Vcc/(Rc+Re)=18V/(3300+510)=4.72mA.

At saturation Vce=0.

Can anyone explain this please?

Benedict said:   7 years ago
Why we have to assume vce=0?

John said:   4 years ago
At saturation, isn't Vce = 0.2V?

Please explain me.

Vce saturation means ic is at its maximum value(saturated).

Ideally, we consider Vce to be zero but in actual it is 0.2 to 0.3 volts for up to 50 mA Ic.
