    Hi

    Please have a look on the following link:
    http://img836.imageshack.us/img836/1554/circuitmm.jpg

    1: I was trying to solve a circuit. I was successful except the part where I was trying to apply the nodal analysis (it's at the very end of the linked scan). Where am I going wrong? By nodal analysis I get Isc = 1/3 A which is wrong. Where did I go wrong?

    2: How would we proceed while applying nodal analysis if the 12V voltage source's polarities are reversed?

    It would be very nice of you if you could help me with the above queries. Thanks.

    Your circuit is cut off at the top of the scan.

    Hi hgmjr

    Yes, you are correct; the circuit is cut off.

    But the cutoff part only contain a 8Ω resistor.
