Question

what is eletroplating? on which effect of the electric current is it based ? why is it done?​

Answer 1

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. The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution of a salt of the metal to be coated; and the anode (positive electrode) is usually either a block of that metal, or of some inert conductive material. The current is provided by an external power supply.

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.

Electroplating is widely used in industry and decorative arts to improve the surface qualities of objects—such as resistance to abrasion and corrosion, lubricity, reflectivity, electrical conductivity, or appearance.

hope it helps!!!! Mark me as brainliest!!!

Answer 2

$\huge\fbox\orange{Answer}$

Electroplating is the process of covering an object with a thin layer of metal by electrochemical deposition.

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.
