Answer:
n = 21.85 x 10¹³
Explanation:
Current is formed by the flow of free electrons in a conductor . It is defined as rate of flow of charge per unit area .
If the given current represents n electrons flowing through a unit cross- sectional area per unit time
n x 1.6 x 10⁻¹⁹ = 35 x 10⁻⁶
n = [tex]\frac{35\times10^{-6}}{1.6\times10^ {-19 }}[/tex]
n = 21.85 x 10¹³
