    QUESTION-1
    Are the concepts of supernode and supermesh valid on dependent sources as well?
    If we have a dependent voltage source between two nodes and none of the two nodes is ground then will we consider that dependent source as supernode while applying KCL?
    Similarly if we have a dependent current source and one of our mesh is opposing its direction do we have to use a supermesh?



    QUESTION-2
    How to apply KCL on this ground node?
    Here is the circuit

    Is this KCL equation correct for ground node?
    i(15ohm) + i(10ohm) = i(5ohm)



    QUESTION-3
    How to solve this small circuit?
    Find "V" and the "current through 3000ohm resistance" in this circuit.

    This looks a lot like homework, MrScience. Is that what it is?

    Its not homework.Im having much more complex circuits in my homework,im asking because im having confusion regarding these concepts.Once i make these things clear i will be able to solve the bigger circuits.
