# The current strength in the metal is 10A. How many electrons pass through a metal in 5 minutes

We translate the values from given to the SI system:
t = 5 min = 300 s.
The expression for determining the current through the charge is:
I = q / t
The charge is determined from the number of electrons and the elementary charge:
q = N * e, where N is the number of electrons, e is the elementary charge e = 1.602 * 10 ^ -19 C.
Substitute this expression into the current strength:
I = q / t = N * e / t
Let us express N from this expression:
N = I * t / e
Substitute the numbers:
N = I * t / e = 10 * 300 / 1.602 * 10 ^ -19 = 1.87 * 10 ^ 22.
Answer: 1.87 * 10 ^ 22 electrons flow through the metal.
