*high school trauma crippling back in*

Always hated diagrams

Well the letter math hasn't gotten this complex and I'm through with all the schooling the gov't system here has to offer xD

looking at those few equations shown (on this 5-question test) makes me squirm


nanoff, you undercover nerd

god this is giving me quantum flashbacks

I like Rossi's name! What is the class about?

Physics.
A PN junction is the result of putting p-type and n-type semiconductors together (p is positive, with an excess of holes where electrons should be; and n is negative, with an excess of electrons). Boundary potential is the electric tension that results from putting the two together. PN junctions only allow electrical current to flow through the junction in one direction, so they're useful for building diodes and transistors.
The band diagram Walter drew describes the possible (and forbidden) energy levels for the electrons in the junction. His diagram is missing the gap between valence and conduction bands, which is a big fucking mistake and shows that you don't really understand what you're doing.
Calculating boundary potential is not particularly difficult, though, it certainly wouldn't be a final exam question. I wanted to do something accurate enough because I know there's a lot of furries in STEM that will notice if I'm just scribbling nonsense, but I didn't feel like digging through my college notes to get a more complicated one.

"there's a lot of furries in STEM".

This is a threatening sentence.

It's a well documented phenomenon. Both attract the same kind of internet introvert, it's no surprise there's a lot of overlap.

i mean even if he missed a single day he could have gotten help catching up from a friend or just picked it up from the next time he showed up cause the class could have used the diagram or formula form the class he missed
thats normally how i had to do it if i missed a class

Oh sweet circuit diagrams?

Aaaaah so it's not the petty jerk kind of teacher, more like overly dedicated and maybe a bit too relentless?

How funny... I've been recently getting into electronics as a hobby. I love your comics!

Those equations are crazy xD

That's the face of someone holding back a tantrum

I hated this so much never did it once, I only wrote the answer and the teacher never took away any points and just gave the grade if it was correct.

Dude fuck that guy

He's left handed!
