Kirchoff's Rules

  1. Apr 14, 2008 #1
    This is a problem I had for homework. I want to make sure I did it correctly.



    (a) Determine the magnitude of the current in the circuit and
    I = (30-10)V / (27+5+8+12)Ω

    (b) The magnitude of the voltage between the points labeled A and B.
    Vab = 30V - .3846A * 27Ω
    = 30V- 10.3842V
    = +19.6158V

    (c) State which point, A or B, is at the higher potential.
    Point B is 19.6158V higher than A
