In the case of a car battery, the following is added: 100 Ah, 12 V
So how many electrons (in mol) can flow in 5 hours?

Solution:

1. Note: the number the flowing electrons is independently of the time, it [translation unavailable] thus not on it at, whether or not the total loading in 5 h or also only in a hours flowing
2. Note: the additionally A (amplifiers) is a indication, how many electrons per [translation unavailable] flow can: 1 C/s = 1 amplifiers
It holds general: a battery with 100 [translation unavailable] can z.B. 10 hours with 10 amplifiers operated are, or 1 hour with 100 ampere etc. Not to be confused or overlooked: ampere is the indication of a charge per second (more accurately: 1 coulomb per second)
In principle, the Ah indicator is nothing more than a hidden Coulomb or charge indicator:
1 C = 1 A·s = 1 A·h/3600 = 0.000277 [translation unavailable]
100 Ah is therefore 360000 Coulombs
The charge of an electron is 1.602·10^-19 C. So a Coulomb is equal to 6.242·10¹⁸ electrons (per second !)
In total are thus 2.24·10²⁴ electrons = approx. 3.73 mol electrons
