Basically I want to Calculate the internal resistance of a solar cell.
I set up a circuit with a voltmeter across the solar cell and an ammeter and variable resistor in series with the solar cell. The variable resistor is the load.

As i change the resistance the value of current changes which is GOOD
However the Voltage stays the same BAD
This results is a graph with a horizontal Line implying that internal resistance is 0. BAD
I need the current and voltage to change i think to get a graph which will be able to give me the EMF and Internal resistance.
Could some one please explain how this is done
Thank you very much
