Answer:
[tex]9.6\cdot 10^{-18} A[/tex]
Explanation:
Current is defined as
[tex]I=\frac{Q}{t}[/tex]
where
Q is the charge passing through a given point
t is the time interval
The SI unit of the current is the Ampere (A), where
[tex]1A = 1C/s[/tex]
which means 1 Ampere is 1 Coulomb per second.
The charge of 1 electron is (in magnitude)
[tex]e=1.6\cdot 10^{-19}C[/tex]
So, the charge of 60 electrons is
[tex]Q=Ne=(60)(1.6\cdot 10^{-19})=9.6\cdot 10^{-18} C[/tex]
Therefore, if there are 60 electrons passing per second, the current is
[tex]I=\frac{9.6\cdot 10^{-18} C}{1 s}=9.6\cdot 10^{-18} A[/tex]
