Introduction
Does An Electrolyte Behave
Like A Resistor?
Aim
To see the relationship between the Current and the Voltage for a liquid.
Circuit Diagram
Anode Cathode
Copper Sulphate (CuSO ) solution
Method
This experiment was done as a demonstration. The results were obtained by adjusting the variable resistor to give a range of readings from the ammeter and voltmeter. These

Conclusion
We could of collected more evidence towards the resistance of a liquid by doing more background work and further work. Some further work would have been trying to find out the outcome of the tests if we increased the voltage going into the circuit. We could have tried different solutions, e.g. Salt Water. We could also have tried the solution at different strengths, weak or strong, e.g. 0.5M.
