1. The problem statement, all variables and given/known data Hi, I need to calculate the voltage drop in an n by m grid. There are resistors 4 resistors connected to a square; R1 for horizontals and R2 for verticals. There's a voltage applied at point B and point A is grounded. I need to create a MATLAB function that will solve for the voltage and display it in a matrix. 2. Relevant equations Kirchhoff Law V= IR 3. The attempt at a solution I1R1 - I2R2 - I3R1 + I1R2 =0 (That's the equation for one of the squares), using this logic to solve for one, I can solve for all. But, how can I automate it for a n x m grid?
