Answer : The number of electrons transferred are,
Explanation :
First we have to calculate the charge on electron.
Formula used :
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:
Now we have to calculate the number of electrons are transferred.
Formula used :
where,
n = number of electrons transferred = ?
Q = charge on electrons = 75 C
e = charge on 1 electron =
Now put all the given values in the above formula, we get:
Thus, the number of electrons transferred are,
