I'm still getting help up on the differences in potential portion of this post. Forget my theoretical circuit going straight to earth. What if the end wire landed in a bowl of dirt? Why can't you simply drain all your current there? What is it about the (-) terminal that I'm not...

Hello all, I have a fundamental question regarding batteries/power supplies that I've been wrestling in my hand. Essentially, what I'm stuck on is this- Why can't you create a simple circuit going from the + terminal of a power supply, through a lightbulb, and straight to ground (Earth)...

Hello, could someone please verify the proper way to supply power to this particular DAC chip: http://focus.ti.com/lit/ds/symlink/dac813.pdf Do I need to supply both +15 V and -15 V into +Vcc and -Vcc respectively? Or do I just supply +15 V to +Vcc and have the negative return lead of that...

Oh, I see. It's a shift, correct?

I don't understand sin(x+ pi)= -sin(x). Is that an identity I am forgetting about?

\int \int \int cos(u + v + w)dudvdw (all integrals go from 0 to pi). I've tried using u substitution for each integral but I end up with a huge integral.
