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 results are shown in results table and the graph. Results Voltage Current (A) Average Current (V) 1st Test 2nd Test 3rd Test (A) 0 0 0 0 0 1.0 0.14 0.12 0.17 0.14 2.0 0.30 0.26 0.36 0.31 3.0 0.46 0.42 0.52 0.47 4.0 0.67 0.60 0.70 0.65 5.0 0.71 0.83 0.86 0.80 Conclusion The graph is showing a straight line through the origin. This means that as the voltage increases, the current also increases uniformly. A graph of Voltage and Current for a resistor was the same, when I did the experiment. This means that the liquid behaves like a resistor. Which was what we were trying to find out. In a liquid, a current is the movement of ions. In Copper Sulphate (CuSO ) solution the sulphate ions are negative and move to...
