how can you tell the difference between a silicon and germanium diode? i know the voltage has something to do with it, but then if the voltage has something to do with it how can you tell if it forward or reverse biased? After that how can you tell a zener diode apart from those two? iso help plz i have a test on this tomorrow and i cant find anything on the internet that will answer this question...

just play CoD all night and forget about the whole thing

muhahahaa!!

i would agree with you on this just no xbox atm anyways i figured it out... now i just have to figure out how to identify a malfunction in a flip flop circuit

I agree with Mike. CoD is the way to go. CoD6 ftw!

i know im a little late, but i know the answers

silicon diodes are used more than germanium because theyre more stable. because germanuium is more unstable, it results in excessive reverse current.
you need 0.7V to conduct a diode. forward bias acts as a closed switch, reverse acts as open.
zener diodes operate in the reverse breakdown region.
depends on how you want to tell these apart. the schematic symbols will be different, also their characteristics.
