Internal Resistance 

This program is about the internal resistance of a battery. The battery is used to drive a current through a resistor. A digital voltmeter measures the emf of the battery and the pd across the resistor when the current flows. You can change the resistor,  record your readings and plot them on three graphs. The theory is given and internal resistance is calculated for you. This is an experiment you should do for real - but this simulation should get you prepared.
