- Make the connections as shown in the figure
- Measure the voltage with an without the 1k resistor connected
 
The voltage drops when load is connected. This is due to the high internal resistance
of the cell, part of the voltage drops inside the cell itself when current flows. 
An ideal cell should have zero internal resistance.
