Here is my updated drawing. I'm confident that I found all the currents and that the junction equations are right, but the loop rule equations confuse me... I'm not sure where the currents that don't pass through resistors go in the loop equations.

Homework Statement Given the drawing, calculate the current going through the 2Ω Resistor and then calculate the difference in electric potential from point a to b. Homework Equations V = IR juction rule: ƩI = 0 = Iin - Iout ƩV = 0 The Attempt at a Solution Well, I attempted to draw all the...

I just went on fearofphysics.com (lifesaver) and have realized my error. I had the distance squared for one fraction, but not the other one. Thank you very much. Edit: It WOULD be one of those errors.

Homework Statement Four positive charges are located on the corners of a square of side-length a. The charges are A=4, B=2, C=8 4q----a----q |------------| a-----------a |------------| 2q----a----8q Determine the magnitude and direction of the electric field experienced by charge q in terms of...
