Hi Eric,
I know that when ID = 0A, VD = VBB = 5V while when VD = 0V, ID = VBB/R = 5mA
That's why we have the load line 5V and 5mA. I have go though internet and reference material, they just mentioned 5V-5A load line. The other load line whereby 4V-4mA is weird for me. I really can't figure out why it exist here??
If what you say that 4V-4mA is for the load line for diode, that's mean the diode current should be 4mA while the voltage across load resistance is VR = ID x R = 4mA ( 1k ) = 4V
Let say I would like to get he power dissipated in the diode is that mean P = ID VD = 4mA ( 4V ) = 16mW
Please correct me if I'm wrong,
Really need your kind help on this,
Thanks & Best Regards,
Gilbert
