The flow of current in solids is due to​

Answer 1

Answer:

The flow of current in solids is due to electrons.

Answer 2

The correct solution in context to current flow here is due to ELECTRONS.

• Solid substances or solid matter are made up of atoms. These atoms have constituents like electrons and nuclei which contain protons and neutrons.
• The electrons are the negatively charged constituents or species that move inside the atoms. The positive species is tightly bound in nuclei of the atom therefore it doesn't move.
• The flow of current is basically the result of the movement of charged species in the matter.
• When a potential difference is applied to the solid that is conductor the electrons start drifting from lower potential to higher potential or towards the positive terminal of the connected end of the external source.
• Therefore in solids current flows as a result of the movement or flow of electrons.
