Terminal voltage and current flow

  1. Mar 30, 2014 #1
    1. The problem statement, all variables and given/known data

    20-40alt.gif

    (a) Calculate the magnitude and indicate the direction of flow of current in Figure 20.40. E2 = 19.0 V and r2 = 0.55 Ω.

    (b) Find the terminal voltage of each battery.



    2. Relevant equations

    V = Ir

    3. The attempt at a solution

    I found the answer for part a to be 4.52 but i don't know how to get the second one.

    I don't understand the question. It looks like you are given the battery voltages...
