Any engineering buffs out there want to tackle this one?
Wow -
it's been a while since I've posted. Why do stupid people insist on trying to add me as a "friend" on face book and Myspace? If you were really a "friend" of mine.... I would have added you already.
Argh. Stupid. You know who you are. I'm not your friend, I don't want to be your friend, and I'm not friends with any of your friends so stop sending me requests!
New note: classes are going really well. I'm getting my arse handed to me in Math class but to my credit I have straight "A's" in everything.
I start the worst math class in a few weeks (3 to be exact). We'll see how that goes.
Right now I'm still trying to figure out what happens in an open circuit that's parallel. I can't for the life of me visually see... why resistance goes up, and current goes down if one of the resistors is bad.
To me: I think of it like this... if you have a bad resistor then wouldn't your resistance go down, and current go up? If there is less resistance wouldn't you have more current flowing through the circuit?
It makes no sense. I know the math is correct
If you have 640 ohms, in R1 and 720 ohms in R2, and 330 ohms in R3 - then total ohms for parallel would be 640/1/x + 720/1/x + 330/1/x) = {answer}/1/x = 167
so 167 would be your total resistance for a parallel circuit. Let's say 240 is total volts(E) for the whole circuit.
If 167 = R, and E = 240, then I (current) would be = 1.43 amps.
Let's say the 330 is bad - then I of R3 would be 0, and R3 would be zero as well. E would remain at 240 (according to rules of parallel).
So... I know- mathematically speaking that Rt would now be: 338 ohms. And your total Current would now be: 710milli amps.
See! The resistance goes up, and the current goes down. WTF?????? In my head I can't make the connection (no pun intended.) To me, I would think that {R} would go down and {I} would go up. Makes NO G/D sense to me.
New note:
JK turned 25 this year. For the B-day celebration we went to M. Sun to see Kathy Griffin. Holy cow... hysterical. We had a blast. But that place is one big G/D circle and we kept trying to find the exit... and kept going around and around and around... proof that neither one of us can find our way out of a paper bag. hahahaha. Oh the fun. Kathy Griffin is hysterical. She's so funny. I laughed so hard that my cheeks hurt.
