What is Internal Resistance of EMF Sources about?

This document provides instructions for an experiment to investigate the internal resistance of a potato battery cell. Students are asked to assemble a potato battery using copper and zinc electrodes inserted into a potato. They will then connect the battery into a circuit with a variable resistor to measure the potential difference across the battery and current drawn. By varying the load resistance and recording the potential difference and current, students can create a graph of potential difference vers
