Answer:
The electrons are moving through the superconductor per second.
Explanation:
Given :
Current A
Charge of electron C
Time sec
From the formula of current,
Current is the number of charges flowing per unit time.
Where number of charges means in our case number of electrons
Therefore, electrons are moving through the superconductor per second.
