I = q/t
Let n be the electrons per second.
q = ne
I = ne
4.8 = n x 1.6 x 10-19
n = 4.8/(1.6 x 10-19)
n = 3 x 1019
Thus, number of electrons passing per second through conductor is 3 x 1019.

- The flow of electrons is opposite to the direction of the flow of current as electron is negatively charged . Then why current is defined as the flow of electrons through the conductor though current travels from positive to negative terminal.
- If charge on one electron is 1.6 x 10 -19 C. Calculate number of electrons required to constitute 1A of current in 1s.
