a current
Asked by mdasifannu | 04 Jul, 2021, 10:37: AM
Expert Answer
I = q/t 
Let n be the electrons per second.
We know, 
q = ne
Thus,
I = ne 
Thus, 
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.
