Question

Faraday constant F, Avogadro number N and electronic charge e are related with each other by :

• A. $F=\frac{N}{e}$
• B. $F=\frac{e}{N}$
• C. $F=Ne$
• D. $F=N{e}^2$

Answer 1

The correct option is C $F=Ne$

Answer is C.
The Faraday constant, denoted by the symbol F and named after Michael Faraday, is the magnitude of electric charge per mole of electrons.
The constant F has a simple relation to two other physical constants:
F = Ne
where, N is the Avogadro constant (the ratio of the number of particles N to the amount of substance n - a unit mole), and e is the elementary charge or the magnitude of the charge of an electron. This relation is true because the amount of charge of a mole of electrons is equal to the amount of charge in one electron multiplied by the number of electrons in a mole.
