Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An example of a good conductor is
A
copper
B
sand
C
plastic
D
None of the above
Explanation: 

Detailed explanation-1: -Copper is used widely in all kinds of electrical wiring which can provide a hint that it is a good conductor of electricity. The reason copper is a good conductor of electricity is that it has a good amount of free electrons which can conduct electricity.

Detailed explanation-2: -Copper and aluminium are most frequently used as the electrical conductors in electrical cables due to their low resistance and excellent conductivity.

Detailed explanation-3: -Typically, metals, metal alloys, electrolytes and even some nonmetals, like graphite and liquids, including water, are good electrical conductors. Pure elemental silver is one of the best electrical conductors. Other good electrical conductors include the following: copper.

Detailed explanation-4: -Copper is considered to be a conductor because it “conducts” the electron current or flow of electrons fairly easily. Most metals are considered to be good conductors of electrical current. Copper is just one of the more popular materials that is used for conductors.

Detailed explanation-5: -Copper. One of the most commonly used metals to conduct electricity is copper. As a material, copper is pliable, easy to wrap or solder, which makes it the best choice when large amounts of wiring are needed. Copper’s core electrical function is related to the transmission of electricity and power generation.
