When I'm doing calculations, yes.
What do? This has gotten me lost already.. http://img178.imageshack.us/img178/8056/532problemo.jpg

I am not sure how to calculate the current for the next series of resistors. I was thinking 3.44404-1.40v-0.200v-(.2A * 2ohm)
But I get a different answer than the book when I do I = V/R for the 40+3 ohm parallel resistor, and so I am not sure if I did it right.

replace all those voltages with Vr# (voltage across resistor #) so i don't have to go through your work.

uh, done. But still, I don't get what I am doing wrong.
When I calculate the current for the resistors I get it wrong. I get I=V/R which is I = 1.4404/43 and I get 0.0334976744 A. Book has 35.7 mA. I'm off quite a bit.
Probably doin' it rung. D:

Hopefully never? This is like the last time we're doing any homework with circuits. We're moving onto thermodynamics now. We did a tiny-tiny bit this week and so I have two problems on that to do after this one. We didn't really cover much of anything this week.
Eh a quick look over says the resistance is right, the current through the first resister is right. That the resistors that should have the same current do have the same current. So unless you messed up some algebra its going to be right.
Oh and btw never ever trust the book unless the proof or teacher says the book is right.
Also thermo even low lvl thermo is going to make that stuff look easy.

You seriously need to stop with these threads you try to play off as you needing help with your work. If you need help just ask. You say you're confident so a confident person would just ask straight out, not create a thread then throw in your problems like you always seem to do.

A witty person realizes that would never get views nor responses when the poster is such.
The lure of my threads is me.

Yes to ridicule you. Are you really a girl? You love any attention like a highschool girl. Whether it's good or bad attention, you don't care.
This is the basis of all Trident posts, he can't get attention in real life, so he does it here. He craves it. I don't completely blame him, a lot of people (mostly kids, teenagers) go through a super angsty/whiny phase before they mature and realize how much of a douche they were. It just seems that Trident refuses to move past this phase. Perhaps one day.
