Faraday’s Constant

Definition

Faraday's constant represents the total electric charge carried by one mole of electrons. It is approximately 96,485.34 coulombs per mole of electrons.

Analogy

Think of Faraday's constant like a conversion factor in a recipe. If you know that one egg equals about 50 grams, then if you need to use 200 grams of eggs, you would need four eggs. Similarly, Faraday's constant tells us how many coulombs (units of electrical charge) are in one mole of electrons.
