Solve function for Supernode Circuit Analysis

  1. Oct 9, 2013 #1
    I am using a TI-89 Titanium ROM Version 3.10

    I can use solve() readily for N equations and N unknowns, however:

    I am trying to use the solve() function for Nodal Analysis with a Supernode

    As you may recall, this means more equations than variables:

    For example: (this is slightly modified from the real problem)

    1] v1/2 + (v1-v2)/3 - 9 = 0 --> I am storing this STO > n1

    2] v2/6 + (v2-v1)/3 - 7 = 0 --> I am storing this STO > n2


    s] v2 + 5 = v1

    or v1 - v2 - 5 = 0 --> I am storing this STO > n3

    The supernode adds one more equation but there are only two variables


    solve(n1 and n2 and n3, {v1, v2})

    returns -> false

    This may be a trivial fix or more complicated, but I cannot see a workaround

    How do I use solve() when there are N unknowns and > N equations ??
