Question

6.
State the meaning of the terms:
(a) Electro-magnetic induction
(c) Electrodes
(b) Electrolysis
(d) Electrorefining of metals

Ans-Electro-magnetic induction :- Electromagnetic Induction is a current produced because of voltage production due to a changing magnetic field.

✴ Electrolysis :- Electrolysis is defined as a process of decomposing ionic compounds into their elements by passing a direct electric current through the compound in a fluid form.

✴ Electrodes :- The electrode, it is any substance that is a good conductor of electricity and these substances usually connect nonmetallic parts of a circuit for example semiconductors, an electrolyte, plasmas, vacuum or even air.

✴ Electrorefining of metals :- Electrorefining is a process used to make impure copper pure. The smelting process takes copper ore and processes it into metal. This metal (sometimes called "blister copper" contains other metals. These other metals often include gold, silver, arsenic and others.​

Answer 1

Answer:

I think you have the answer is your question.

Answer 2

Answer:

Electro magnetic induction= the phenomenon if induced current and induced emf due to the change in magnetic flux linked with a closed circuit.

Explanation:

Electrolysics=chemical decomposition produced by passing an electric current through a liquid or solution containing ions

Electrodes a conductor through which electricity enters or leaves an object

Electrolytic refining it is the process of refining of metal in which impure metal is made the anode and a thin strip of pure metal is made the cathode. A solution of metal salt is used as an electrolyte
