1 coulomb is that quantity of electric charge which exerts a force of 9 x 109 N on an equal charge placed at a distance of 1 m from it.

It is the fundamental unit of electric charge.
denoted by C.

It is equal to the charge transported in one second across a conductor in which there is a constant current of one ampere. 
Charge = Current x time 
Thus, 
1 Coulomb = 1 Ampere x 1 second 
Thus, 
Coulomb can also be written as Ampere - second.

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.
