How much is a Coulomb, really?

$begingroup$ A one Farad capacitor at one volt has one Coulomb on it. Now, one Farad is a big capacitor for most electronics applications, but you can go to Digikey and find 6000F capacitors in stock. And, at 1 volt nothing will happen if you touch it. Yet, a 10mA current through you can kill you. It isn''t simple. $endgroup$ –
