Just wat to alert you that the current source has it's "arrow" upwards but the plus signal is at the bottom side of the current source symbol... I don't know if this has any influence in maths behind the resolution!Hi,
Sure no problem. I was going to post an exact response curve too but was holding off because that might reveal too much right now and i assumed you wanted to figure this out for yourself.
Once you're done i can post that if you like.
Hello MrAl...Hi,
Yes i see what you mean about the two signs inside the current source on the left. The arrow points up, but the tip is marked (-) and the bottom marked (+), which makes no sense.
Normally the current arrow is drawn in the direction of current flow for conventional current flow, not electron flow.
You are going to have to ask your instructor if he/she meant to show the reversed sign for the reason of reversed flow, or it just shows that the starting current was negative (-5ma).
There is no way we can interpret something off the all like that.
Note that in Eric's circuit he assumed the same thing as i did.
So find this information out first. Note that if the current is reversed it changes the whole problem because then we really would be starting with a +5ma current which means the circuit would start out with BOTH diodes conducting, then gradually they turn off one by one. This is completely different than before.
Ok...
This is how we was supposed to solve the diodes problem correctly.
See attached pics!
One of the other 2 version was also corrected but I should convert Vin into Is.
