electrolytic cell

I have a question, is there a formula to calculating the average current which flows through an electrolytic cell, using datas that include the following:

 

(a) changes in concentration of [OH-]

(b) the volume of the solution

© the time of the electrolysis

 

my obtained datas for those three parts are:

(a) 4.2e-3 M

(b) 30 mL of KI solution

© 18 minutes

 

I think it has something to do with figuring out moles of the substance in the solution and from there the moles of electrons tranferred and thus its combined charge. But how do I do it?

Look up Faraday's Laws of Electrolysis.
