Internal Resistance of Battery Problem
Internal Resistance of Battery Problem
You have varied the resistance of your circuit and collected data on the current through the circuit and the voltage across the terminals of the battery powering your circuit. Your data has been plotted (Terminal Voltage vs. Current). From this graph, determine the maximum current, the internal resistance of your battery and the electrochemical potential of your battery.
