Question

The power required for electro-deposition is
AC and very low voltage
AC and high voltage
DC and high voltage
DC and very low voltage

Answer 1

Answer:

DC and very low voltage is the correct answer.

Explanation:

The process which uses electric current to reduce dissolved metal cations so, that a thin layer forms on electrode like a coating is called electroplating.

We use electroplating so, as to that the object can be protected from corrosion, wear resistance etc.

Electrodeposition is the process used in electroplating.

In this the object which needs coating is placed at cathode and anode is placed with material which will be coated on object.

Cathode and Anode are immersed in electrolyte which have dissolved metal salts and also having ions which helps electricity to flow.

Direct current(DC) gets applied on anode. The rate at which material gets coated on object is equal to the rate of the material at anode getting dissolved in electrolyte.

Answer 2

The power required for electro - deposition is:

DC and very low voltage.

- Electroplating can be defined as a process in which we use an electric current so as to reduce the dissolved metal ions such that they make a thin covering (or coating) of metal on an electrode.

- In other words, it is also known as electroplating.

- Generally, we use direct current for the electro deposition and that too of very low voltage.

- Hence, the last option is the correct answer.
