Voltage/current divider

  1. Oct 28, 2013 #1
    1. The problem statement, all variables and given/known data

    Calculate ig, i0, i1, i2, Vx using current and voltage divider.


    3. The attempt at a solution

    You were doing fine until you got to the calculation of Vx. There's no way a potential drop in the the circuit can be larger than the supply voltage...

    Yes you're right. I didn't pay attention to that.
    V should be 1.25V(voltage divider on both 100 ohm resistors) and Vx = 1.125V (voltage divider between the 90 and 20//20 ohm resistors)

    Muuuch better :smile:

    You could also have just multiplied your i3 by 90Ω.
