So in this case, is the voltage on the capacitor zero at t=0+ or is there some initial charge? It is zero because there is no source when t<0, right? From your diagram, how would I be able to calculate v(∞)? Capacitors act as open circuits to DC, right? So isn't that an open circuit?

Oh, I just realized the question is asking for t≥0. Opps. I've redrew the circuit for t≥0 but I'm not quite sure I understand what you mean. How does the capacitor look like a voltage source if it's not in the circuit diagram? How do I get the voltage of the capacitor if it's not in the...

Homework Statement Attached. Homework Equations The Attempt at a Solution Attached. I am looking at the circuit at t<0. I need to calculate v(0) but I'm not sure how to apply nodal analysis when you have a capacitor in the circuit. Do capacitors follow ohm's law?

This probably will make me sound like a bad person but here it is: good. It increases my chances of getting into a good college. :)

Homework Statement The lab is attached. I've also attached the pre-lab just for the diagram. Homework Equations The Attempt at a Solution Can anyone think of some good errors for this lab? We ended up with ~80% error. I've thought of two: 1. Adjusting the potentiometer so...

Electives: literature, politics, and geography. Discipline: computer engineering Thanks for the heads-up.

So today I found out that I am not good at my electives. Do employers care more about cumulative GPA or my major GPA?

I think it's akin to asking how many children Newton had on a physics exam. It was probably mentioned somewhere in the textbook that he was never married and therefore the prof. would be asking material from the textbook. Another solution is to write some sort of algorithm to parse all the...

Accept the hit to the GPA like a man/woman. Protip: make sure you answer some questions incorrectly. If you get 100% it will be too suspicious. If you get 90% you'll still get the 4.0 depending on your university's GPA scale but the prof won't be on your butt.

Thanks. I make so many dumb mistakes. :(

That's weird: http://www.wolframalpha.com/input/?i=m%5E2-k%5E2m%3D0 Going to try plugging it in. Edit: Oh wow. You're right. I'm an idiot. Lol

Sorry for wasting your time, but I already posted:

Why is the second one not a solution? If you convert the original DE into an auxiliary equation, you will get roots: m1=0 and m2=k2

Homework Statement Homework Equations The Attempt at a Solution Are you allowed to do that where you just apply L'H an infinite amount of times?
