Expert Answer:

Conventionally  it is said that an electric current flows from positive end of a cell or battery to the negative end through the closed circuit. In fact, in a conductor it is the electrons which drift from negative end to the positive. We call this current as electronic current. The electronic current is equivalent to conventional current flowing form positive to negative end of wire.
                  
                 
The cell is the source of electrons. It has two ends, one positive end(cathode) and the other negative end(anode). We know that like charges repel each other and unlike charges attract each other. Because of this reason when the positive end of the cell is connected to negative end of cell by a conductor, the electrons are drifted from anode to cathode. This flow of electrons is called electric current.
