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... Thanks.
