Electric current is produced due to the flow of electrons. It is defined as the rate of flow of electrons through a cross section of a conductor. Let us derive a relationship between current and the number of electrons flowing through the conductor.
We know that
...............(1)
also
................(2)
Combining 1 and 2 we get
This is a relationship between amount of current flowing with the number of electrons flowing.
Illustration: A total of electrons flow through a current carrying conductor when connected through an external power supply for 20s. Find the value of current in the conductor.
Solution: Given, Total number of electrons,
electrons
Time, t = 20 s, Current, I = ?
Thus, the current through the conductor is .
