(n.) The standard unit of quantity in electrical measurements.

Formerly called weber.

How much this is an underestimate depends upon how much hydrophobic binding is greater with the uncharged compound.
(19) The coulomb is a single unit of charge while c is the velocity of light.
(20) The interaction is accordingly primarily, but probably not exclusively, coulombic in origin.
Farad
Definition:
(n.) The standard unit of electrical capacity; the capacity of a condenser whose charge, having an electro-motive force of one volt, is equal to the amount of electricity which, with the same electromotive force, passes through one ohm in one second; the capacity, which, charged with one coulomb, gives an electro-motive force of one volt.
