The number of electrons is 1.9 * 10^20 electrons.
How many electrons move through it?
We know that it is possible to obtain the charge that the electron carries by the use of the formula;
Q = It
Q = magnitude of charge
I = current
t = time taken
Now we have the charge as;
Q = 0.5 A * 60 s = 30 C
Given that;
Q = ne
Q = charge
n = number of electrons
e = magnitude of electronic charge
n = Q /e = 30 C / 1.6 x 10-¹⁹ C
n = 1.9 * 10^20 electrons
