Electroplating is a process of depositing a thin layer of metal onto a surface by using an electric current. This process is commonly used to improve the appearance and durability of metal objects. Electrolysis, on the other hand, is a process of breaking down a substance into its constituent elements by using an electric current. This process is used in the production of chemicals and metals.

These processes are widely used in various industries. For example, electroplating is used in the automotive industry to improve the appearance and durability of car parts. Electrolysis is used in the production of aluminum, chlorine, and sodium hydroxide.

The success of electroplating and electrolysis processes depends on the efficient conversion of electrical energy into chemical energy. This is where rectifiers come in.
