One of my roommates in college was in the electrical engineering
program. They only had to take one semester in thermodynamics. I had to
take 3 semesters of thermo and one in heat transfer. When it was time
for him to take on this subject, he really struggled and I could not
understand why. It feels really funny to be on the other side of the
fence now. I guess this is the karma I'm getting for making fun of him
at the time :)

I know Ohms Law, but how do I take it from there??
