Dear student 
Faraday’s laws of electrolysis are quantitative (mathematical) relationships that describe the above two phenomena. 
Faraday’s First Law of Electrolysis states that the chemical deposition due to the flow of current through an electrolyte is directly proportional to the quantity of electricity (coulombs) passed through it.
i.e. mass of chemical deposition is directly proportional to Quantity of electricity 
Q => m = Z*Q
Where, Z is a constant of proportionality and is known as electro-chemical equivalent of the substance.
Faraday’s second law of electrolysis states that, when the same quantity of electricity is passed through several electrolytes, the mass of the substances deposited are proportional to their respective chemical equivalent or equivalent weight.
Chemical equivalent = Atomic weight /Valency
