    Does Kirchhoff's voltage law give electron flow and current law give conventional flow?

    Thanks for taking the time to help Sammy :) I took the pic down because of that inaccuracy you mentioned. All the loops that I've derived my figures from in my original post go anticlockwise. However I think I've inadvertently done it right. When I originally did it I followed the advice...

    Does Kirchhoff's voltage law give electron flow and current law give conventional flow?

    ach I still don't understand :/ I've just resorted to redoing the voltage equations going clockwise instead of anticlockwise. And that gives me the right currents going down. Thanks anyway :)

    Does Kirchhoff's voltage law give electron flow and current law give conventional flow?

    I don't understand what you're trying to say or how it helps my questions sorry :/

    Does Kirchhoff's voltage law give electron flow and current law give conventional flow?

    Hi, Ive trying to work through Kirchhoffs voltage and current laws. Ive so far calculated: Current in Loop one (I1): 3 Amps going anticlockwise Current in Loop Two (I2): 4 amps going anticlockwise Current in Loop Three (I3): 8 amps going anticlockwise R1: 5 amps going up = (Current...

    Basic DC Circuit/Kirchoff problem with 2 power supplies

    so the method I've used in finding the power dissipated across R3 is correct? And I've solved it? :)

    Basic DC Circuit/Kirchoff problem with 2 power supplies

    http://img546.imageshack.us/img546/5104/shtuff.jpg Uploaded with ImageShack.us I've been asked to find the power dissipated across R3. I'm just wondering if I'm right in my method so far? Loop One: -6v + R1(I1) + R3(I1-I2) = 0 I1 = 1.0471698Amps Loop Two: -1.5V + R2(I2)...

    Solving a system of three equations with large coefficients

    Yeah I threw away the method I used in my original post. I haven't done it the same way as you guys, (I got values for A,B,C after about 9 steps while you guys seemed to have done it in 5 or 6) However battling the logic out for myself has helped me understand the process better, and I...

    Solving a system of three equations with large coefficients

    I've been looking on youtube to try and learn how to do these more complex equations but all the examples use small numbers that easily fall into place. Ive got Equation One: 48A - 32B - 2C = 0 Equation Two: -32A +46B - 11C = 0 Equation Three: -2A - 11B + 13C = 54 Ive mulitplied...

    Basic DC Circuit/Kirchoff problem with 2 power supplies

    http://img823.imageshack.us/img823/9775/picture2mq.jpg Uploaded with ImageShack.us Hi I can't get my head round Kirchoffs law. I've been alright with series and parallel circuits with one voltage supply, but I've been given a problem with two voltage supplies. Would anyone be able...
