Q = It = ne
I am not familiar with the above equation. Is it the related to the equation It = Fn ? |

Q = It is the definition of current since current is the rate of charge moving:
I = Q/t
And for your other question: please define the variables for Fn. Because it sure looks alot like ne! |

Q = ne
Q = total charge
n = number of electrons
e = electronic charge (a constant which you do not need to memorize; 1.6*10^-19)
PS: regarding the latter, keep in mind that 1 electron volt = 1 eV = 1.6*10^-19 joules |
