Faraday's Second Law of Electrolysis

The amounts of different substances enlightened by the same quantity of electricity passing through the electrolytic solution are proportional to their chemical equivalent weights.

During Faraday's times, there are no constant current sources available. The general practice was to put a coulometer for determining the quantity of electricity passed from the amount of metal deposited or consumed. However, coulometers are obsolete and do not have constant current (I) sources and the quantity of electricity q passed and is given by Q = It

where, Q is in coloumbs

I is in ampere

t is in second.
