Different ways to check the answers

  1. Mar 16, 2008 #1
    1. The problem statement, all variables and given/known data
    What are different ways to check your solutions for simple Resistive Circuits?
    Or even in general cases, how I can make sure that my answer is right?

    I am making very stupid mistakes (mostly algebra problems and using wrong directions),
    so I want to make sure that I don't repeat these mistakes in the exam.
    I am not very familiar with circuits, so I cannot use reality check (in Physics, it's very simple to guess the answer even without doing detailed calculations)

    2. Relevant equations
    I am using Nodal Analysis and Mesh Analysis to solve them

    3. The attempt at a solution

    Here's a checklist I developed:
    # Reviewing Nodal Analysis Questions:

    1. I should write detailed steps (neatly) leaving space between lines
    2. I should simplify my equations before solving them on calculator
    3. After Calculations:
    1. See if I have used right numbers
    2. See if my equations are right
    3. See if my solutions meet with my equations
    * See if I have right directions of currents as indicated by diagram
    4. If time available, use other techniques to confirm my answers
    5. See if power analysis agree...
