Any point in the wire has 1.12 x [tex]10^{19}[/tex]. electrons flow per second.
The current is the quantity of charge Q flowing through a certain point of the wire in a time interval of [tex]\Delta t[/tex].
I = [tex]\frac{Q}{\Delta t}[/tex].
by using this relationship
I=1.80 A, we can find the charge passing any point in the wire in 1 second:
Electric Charge, Q = 1.80 C.
To find how many electrons corresponds to this charge, we should divide this value by the charge of a single electron
charge of the electron = 1.6 x [tex]10^{-19}[/tex] C.
No. of Electrons = Q/q = [tex]\frac{1.80}{1.6* 10^{-19}}[/tex]= 1.12 x [tex]10^{19}[/tex].
