What number of electrons N corresponds to a charge q = -200 μC?
| October 2, 2021 | education
The electric charge can be calculated using the formula:
q = n * e, where q is the electric charge (q = 200 μC = 200 * 10 ^ -6 C), n is the number of electrons, e is the value of the electron charge (e = 1.6 * 10 ^ -19 C).
Let’s express and calculate the number of electrons:
n = q / e = 200 * 10 ^ -6 / (1.6 * 10 ^ -19) = 3600 * 10 ^ 19 = 125 * 10 ^ 13.
Answer: A charge of 200 μC corresponds to 125 * 10 ^ 13 electrons.
