Homework Help: Nodal Analysis of a combo circuit

  1. May 31, 2016 #1
    1. The problem statement, all variables and given/known data

    Attached is a image of the circuit that I am attempting to analyze:

    2. Relevant equations


    3. The attempt at a solution

    So I know I should assign a place in the circuit where I should preform KCL after selecting a reference point.

    I selected the reference point as the 2ohm resistor with the right hand side being V2 and the left as V1

    Would the KCL at v1 be:

    -4+(v1-8)/2+(v1-v2)/2 =0

    and KCL at v2 be:

    (v2-v1)/2 + v2/4 =0

    But I didn't get the right answer. I have not sure now...

    Hi SteliosVas. What you have written looks right. So try again solving these equations.

    What are you given as the correct answer?
