Solving Circuit Diagram

    1. The problem statement, all variables and given/known data

    2. Relevant equations
    No idea

    3. The attempt at a solution
    No idea

    I'm not sure how to solve this or where to look for a solution. I was given this yesterday and have a test tomorrow. The professor has not gone over this at anytime, it's only the second week. Anything helpful would be great, even just what I need to google so I can attempt to solve this.

    P.S. I do not know the solution.

    Try this site. http://hades.mech.northwestern.edu/index.php/Kirchhoff's_Current_and_Voltage_Laws
    Or Google/Wikipedia on Kirchhoff's Laws.

    The sum of voltages around any given loop equals zero. So if you go from - to + in an element, you add voltage. If you go from + to - in an element, you subtract the voltage. The diamond shaped source is a dependent voltage (it is 5 multiplied by the value of I0).


    You might want to take a look at the Navy's NEETS modules, for electricity and electronics. The US Navy has published these and made them available to the general public. Davidson College hosts all 24 PDF's here: http://www.phy.davidson.edu/instrumentation/NEETS.htm

    @TheRealBillNye, your own attempt at a solution is required as per forum rules.
    This much information is sufficient for solving this problem.

    Thanks for the help, would someone mind checking this for me as I don't know the answer.

    That's not correct. Which current is I1?

    How about you just consider the lefmost loop containing the 30V source? Apply KVL in that loop only.

    What is this 18 volts across I1 ? Try a loop around the lower left-hand square of circuitry.

    If you draw the schematic in this way you may calculate ia and ib as function of Vo and then Vo=18 V.
    [5Io=5*2=10V]

    It's easier than that. No need to calculate ib at all. Just apply KVL to the left hand loop.
