Homework Help: Current/terminal voltage

  1. Apr 14, 2010 #1
    1. The problem statement, all variables and given/known data

    http://session.masteringphysics.com/problemAsset/1084694/3/GIANCOLI.ch26.p36.jpg

    Determine the currents I_1, I_2, and I_3 in the figure. Assume the internal resistance of each battery is 1.0 Ohm.
    I1, I2, I3 = __________ A



    What is the terminal voltage of the 6.0-V battery?
    Vt = _____ V


    2. Relevant equations

    I know I have to include Kirchoff's Loop Rule and Junction Rule

    Welcome to PF!

    Hi knobles8179! Welcome to PF! :smile:

    (btw, two h's in Kirchhoff! :wink:)

    That's right … do loop equations for any two of the three loops, and a junction equation, and find the voltage drop across the "r" resistance (which i assume is intended to represent the internal resistance of the 6V battery), and subtract it from the 6V. :smile:
