The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Faraday as a Discoverer by John Tyndall: quantity of water decomposed by the current. He tests this measure
in all possible ways, to assure himself that no error can arise from
its employment. He places in the course of one and the same current
a series of cells with electrodes of different sizes, some of them
plates of platinum, others merely platinum wires, and collects the
gas liberated on each distinct pair of electrodes. He finds the
quantity of gas to be the same for all. Thus he concludes that when
the same quantity of electricity is caused to pass through a series
of cells containing acidulated water, the electro-chemical action is
independent of the size of the electrodes.[3] He next proves that
variations in intensity do not interfere with this equality of
