Ohm''s law states that the current flows through a conductor at a rate that is proportional to the voltage between the ends of this conductor. In other words, the relationship between voltage and current is constant: I/V = const. The Ohm''s law formula can be used to calculate the resistance as the quotient of the voltage and current.
$begingroup$ However you end up measuring the capacity, also consider things like environmental conditions such as temperature.
