As others have mentioned, 1 farad is 1 coulomb per 1 volt. But the rabbit hole goes deeper -- the question then becomes why is 1 coulomb what it is, and why is 1 volt what it is?. Following this rabbit hole to the bottom will eventually lead us to the 7 base SI units, which are units of measure for the 7 physical attributes of our world: distance, …

Measuring the Internal Resistance of an Electrolytic Capacitor
You''ll be measuring the capacitance mostly, and what''s left will be a small fraction of the resistance measurement. You should run the numbers yourself- determine the sensitivity to each value. If you measured with two different (say 2:1 or 5:1) relatively low value external resistors over exactly the same voltage change you might be able to ...

14.6 RLC Series Circuits
This underdamped solution is shown in Figure 14.17(b). Notice that the amplitude of the oscillations decreases as energy is dissipated in the resistor. Equation 14.45 can be confirmed experimentally by measuring the voltage across the capacitor as a function of time. This voltage, multiplied by the capacitance of the capacitor, then gives q(t).
