Power source question

  1. Apr 21, 2007 #1
    1. The problem statement, all variables and given/known data

    - see image

    2. Relevant equations

    I am having trouble figuring this out mathematically...

    I have no idea why but I can't figure it out using V=IR that the circuit on the left has 1/3 the current of the circuit on the right...

    can anyone plz give a mathematical explaination?

    3. The attempt at a solution

    Left : 3Vb = I1 * RL
    Right : Vb = I2 * RL

    then if Vb = 2 and RL = 1, wouldnt that make I1 > I2, by 3 times..

    anyone suggestions?

    Your solution is correct.

    hmm... this question is actually from the book and the answer is in words... it states that the circuit on the right (I2) should be 3x the current on the left (I1), but according to my calculations that is not the case... I cant figure this out mathematically...
