i should find Re so that transistor works in saturation region
also i should find Ib in saturation region
Rc=2kΩ , R1=2kΩ , EB=5V, Vcc=10V, V1=3V, β=100
im really confused with R1 and V1 i don't know what is their function
i know that in saturation region Vce = 0
also from the diagram i can see that
Eb - 0.7 = Vre so Vre = 4.3 Volts
Ie = Vre/Re
if we assume that Ie = Ic
then
Ic = Vre/Re
Ic is Vcc/Rc = 10/2000 = 5mA
so Re should be Vre/5mA = 4.3/5*10^-3 = 0.86 KΩ
but does this Re stand for saturation region?
