so in #1, element 1 follow the psc, since the current is positive, while element 2+3 don't follow the psc, since the current are not positives?

ahhh, I'm so confused..alright. The reference marks for i3 points down, so based on the reference mark, the current is flowing down.

For element 3, P=VI using that given values for element 3, [1(v)][-3(mA)] = -3(mW)

hm... for element three, using P=VI, you get -3, I'm guessing it goes down.

"if the values of voltages + current are as follow, then which elements follow psc", So, I'm not sure if that word "IF" changes stuff. I was working out the KVL and KCL, and the equations weren't working out.

Homework Statement 1) Q. Which of the elements follow the passive sign convention? (psc) http://img401.imageshack.us/img401/3092/pic1r.gif v1 = +5 (V) i1 = +2 (mA) v2 = -10 (V) i2 = +500 (µA) v3 = +1 (V) i3 = -3 (mA) 2) Q. Which of the elements follow the passive sign...

ahh now I get it. Thanks so much for the help, everyeon!

is the relationship, the product over sum rule?

I'm still not understanding about question 1...

For 1, the total resistance will go up. For 2, I checked my textbook, and there is an example that shows a circuit and a equivalent circuit of its original circuit. Turns out, I was wrong. This one is actually True. For 3, that means the total voltage passing through each resistor is equal...

Homework Statement 1.The equivalent resistance of several resistors connected in parallel is always lower than the smallest valued resistor. A) True B) False 2. The following two circuits are equivalent at terminals A-B. http://img6.imageshack.us/img6/1401/circuity.jpg A)...
