1) Electrical Conductivity is an intrinsic property of any given material.
2) Volta made first electric cell in 1800 using Zinc and Copper plates dipped in Sulphuric acid. The cell he made is called a Volta cell in his honour. The word "voltage" is also derived from his name.
3) Process of coating one metal onto other by the process of electrolysis is called as "electroplating".
4) Uses of electroplating:
a) To protect metals from corrosion by atmospheric air/moisture air/chemical environment.
b) To increase conductivity.
c) Ornaments & decoration items.
