Hint:While studying the electrical processes in batteries, the English chemist William Nicholson by chance discovered electrolysis in the 1800s. Some years later, the famous chemist and physicist Michael Faraday developed the electrolysis laws.

Complete step-by-step solution:
Electrolysis is a technique in chemistry and manufacturing that uses the direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is important commercially as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell.
The decomposition potential is the voltage required for electrolysis to occur. Because the word "lysis" means "to separate or break," electrolysis could be translated as "breakdown of electricity" or "breakdown via electricity."
Electrotyping is one of the applications of electrolysis, and it is used to reproduce some craftwork, such as artwork on metals, woodcarving, and gramophone records, among others.
A wax block is used to make an impression of the object. The wax block impression is then coated (sprayed) with fine graphite powder and made cathode in an electrolytic bath containing a suitable salt solution. e.g, copper sulfate.
The anode is a thin sheet of pure metal, such as copper metal. The passage of an electric current causes copper to be deposited on the wax block impression. The wax is removed by melting after a sufficiently thick layer of metal has been formed. The metallic impression obtained can be used to make copies on paper or plastic.
Thus, Electrotyping is an application of electrolysis.

Note: The key process of electrolysis is the exchange of atoms and ions caused by the removal or addition of electrons due to the applied current. The desired electrolysis products are frequently in a different physical state than the electrolyte and can be removed by physical processes (e.g. by collecting gas above an electrode or precipitating a product out of the electrolyte).
