Question

How does the electron and current flow in the Daniel cell?

Answer 1

i)        In the Daniel cell, the electron current flows from Zn to Cu but the conventional current flows from Cu to Zn

ii)        This is because, in the two ends of the wire the potential difference is applied. By applying potential, the positive particles move from higher potential to the lower potential in the true solution

iii)        Whereas the negatively charged particles moves from lower potential to higher potential region

iv)        This concludes the flow of positive and negative particles is in the opposite direction. Here the net current is zero. But this case is not possible

v)        To overcome this problem, direction of current is defined as direction of flow of positive charge and if negative charge is flowing then that current is taken in opposite direction. The two current (positive charge particle current and negative charge particle current) is then taken and added to find net current
