Q1. What is electroplating
Ans. 
Electroplating is a process of depositing a layer of metal onto a surface using an electric current.
• Electroplating involves immersing the object to be plated (called the substrate) into a solution containing metal ions.

• A direct current is then passed through the solution, causing the metal ions to be attracted to the substrate and form a metal coating.

• Common applications of electroplating include improving the appearan...read more
