This document summarizes a physics project conducted by Pranay Kumar Raj to study the various factors that affect the internal resistance of a cell. The project involved experiments to determine how internal resistance is impacted by the distance between electrodes, electrode surface area, electrolyte concentration, and temperature. Test results found that internal resistance increases with greater electrode separation and decreases with larger surface area, higher electrolyte concentration, and increased temperature. The project was conducted under a teacher's guidance and certification was provided upon completion.
