Internal Resistance of a Battery, EMF, Cell Terminal Voltage, Physics Problems

This physics video tutorial explains how to calculate the internal resistance of a battery when connected to a load resistor. It explains the difference between the terminal voltage across the resistor and the emf or electromotive force generated by the cell. This video contains examples and practice problem showing how to calculate the terminal voltage and the battery and the internal resistance of the cell. The terminal voltage of a battery decreases when electric current is drawn from the cell. As the current delivered by the battery increases, the terminal voltage decreases.
