Chemical Effects of Electric Current Test - 1

Explanation:

The substance through which electric current can flow easily is called good conductor of electricity. Metals are good conductors of electricity.

Explanation:

Electroplating is the process of depositing a thin layer of another metal like zinc to prevent corrosion and make more attractive. Cycle handle is electroplated.

Explanation:

The passage of an electric current through a solution causes chemical effect that leads to deposition of metal on cathode.

Explanation:

Plastic is not a good conductor of electricity. Mostly all metals are good conductors of heat and electricity. Copper, Silver is a metal, hence good conductor of electricity. Even Graphite is an allotrpe of carbon, it is also a good conductor

Explanation:

Electroplating is done to make the metal corrosion free and scratch resistance. It also enhances the look of the substance.

Explanation:

The substances through which electric current cannot pass are called bad conductor of electricity. These materials have high resistance.

Explanation:

Air conditioner, mixer grinder and television run on electric current but gas burner used at home does not run on electric current.

Explanation:

Tester is an electrical device used todetermine the presence or absence of an electric volatge (usually (AC) in a piece of equipment under test. A test light is generally simpler and less costly than a measuring instrument such as a multimeter 

Explanation:

Materials like paper, plastic, wood do not allow electric current to pass through them easily are called poor conductor of electricity. Insulators don't conduct electricity at all.

Explanation:

Sea water contains small quantity of salt that allow the flow of electric current through them. Distilled water, alcohol and sugar solution do not contain ions or charge particles.
