How Do Electrical Equations Help Calculate Charge and Electron Flow in Circuits?

[runicle]

Can you please explain me in lamens terms what are these variables names and what they give:
-
1c=6.24 * 10^18
e=1.60 * 10^-19
Q=Ne
Fe=KQ1Q2/d^2
I=Q/T
1A = 1C/1s
-
And How would i do this question with the stuff i have written above this line?
-
A current of 0.82 A flows through an electric lamp for 10 min. In that time how much charge passes a given spot in the filament expressed in
(a)Coulombs
(b)Electrons
-
For (a) i think I need to use 1A = 1C/1s
So C=A*S
-C=0.82 A (600s)
-C=492
But in the back of my book its -492 explain what i did wrong
-
For (b) I think i don't know what to use I'm

1c=6.24 * 10^18
One Coulomb is 6.24 x 10^18 electrons (Sould help you with part b)

Can you please explain me in lamens terms what are these variables names and what they give:

Fe=KQ1Q2/d^2

This is known as coulomb's law
