What are some possible sources of error in this experiment.
Interfacial voltage varies and is different from the center and the edges of the electrode. According to the results that have been gathered, there is a positive correlation between the time it takes to electrolyse an aqueous solution and the rate of electrolysis.

As the electrode voltage increases, the current usually increases too as increasing the voltage makes it easier for electrons to transfer between the electrode and the redox-active species in solution.
