Answer 2

Electrons in the wire flow due to electric potential difference between the two ends of the dry cell.

Explanation:

• A dry cell is a device that changes chemical energy to electrical  energy.

• It consists of an outer case made a negative  electrode and a positive electrode in the centre of the cell and the space between  them is filled with an electrolyte paste.

• The chemical reactions in the battery causes a build up of electrons at the anode. This  results in an electrical potential difference between the anode and the cathode.

• When the two electrodes of the cell are connected via a closed path, then the cell forces the electrons to flow from one end to the other. The flow of electrons causes the current to flow in the closed circuit.

• With the help of chemical reactions, the electrons flow from one end to the other. When two or more cells, connected with correct polarity, more electrons are flowed due to high potential.
