Answer : The number of electrons transferred are, [tex]4.68\times 10^{20}[/tex]
Explanation :
First we have to calculate the charge on electron.
Formula used :
[tex]Q=I\times t[/tex]
where,
Q = charge on electron = ?
I = current = 300 A
t = time = 0.250 s
Now put all the given values in the above formula, we get:
[tex]Q=300A\times 0.250s[/tex]
[tex]Q=75C[/tex]
Now we have to calculate the number of electrons are transferred.
Formula used :
[tex]Q=ne\\\\n=\frac{Q}{e}[/tex]
where,
n = number of electrons transferred = ?
Q = charge on electrons = 75 C
e = charge on 1 electron = [tex]1.602\times 10^{-19}C[/tex]
Now put all the given values in the above formula, we get:
[tex]n=\frac{75C}{1.602\times 10^{-19}C}[/tex]
[tex]n=4.68\times 10^{20}[/tex]
Thus, the number of electrons transferred are, [tex]4.68\times 10^{20}[/tex]
