Eli5 Why is one Farad an impractically large unit? 1 Coloumb of charge is technically the electric charge of 6.24 10e18 charge carriers. And one Farad is by definition this much amount of charge stored across a potential difference of one volt. If related what are Supercapacitors, their application?

Michael Faraday pioneered his work in the 1830s. Back then, a lot of science was performed by wealthy people and not so much institutions. The technical equipment was just not available and whatever they used had to be commissioned using craftsmen. That all said, the equipment was just not that sensitive. There wasn’t much history to know how to make them better. To determine relationships and come up with formulas that were accurate, high energy was needed. So the standard derived through testing is quite high. Today’s electronics require much lower energies. So with capacitors, what is used today in useful electronics are often a millionth or million millionth of the derived Farad.
