What is electroplating ? On which effect of the electric current is it based? Why is it done ?
Answers
Answer:
The passage of an electric current through a conducting liquid causes chemical reactions. The resulting effects are called chemical effects of currents. ... The process of depositing a layer of any desired metal on another material, by means of electricity, is called electroplating.

Explanation:
Electroplating is a general name for processes that create a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current. ... It is also used to purify metals such as copper.
The heating effects of electric current depend on three factors: The resistance of the conductor. A higher resistance produces more heat. The time for which the current flows.
An electric current is passing through a conductor which becomes hot after some time and produces heat. This is due to the conversion of some of the electrical energy that passes through the conductor, into heat energy. This effect of electric current is called the heating effect of current.
