Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A material that does allow electrons to flow through. Low resistance.
A
insulator
B
conductor
C
resistor
D
None of the above
Explanation: 

Detailed explanation-1: -Electric conductors are materials which allow electric current to flow through it easily. All metals such as copper, Aluminium, iron, silver are conductors of electricity.

Detailed explanation-2: -Materials with high electron mobility (many free electrons) are called conductors, while materials with low electron mobility (few or no free electrons) are called insulators.

Detailed explanation-3: -Conductors: Materials that offer very little resistance where electrons can move easily. Examples: silver, copper, gold and aluminum.

Detailed explanation-4: -Materials that allow many electrons to flow freely are called conductors such as copper, silver, aluminium, hydrochloric solution, sulphuric acid and saltwater. In contrast, materials which allow few electrons to flow are called insulators such as plastic, rubber, glass and dry paper.

Detailed explanation-5: -Materials that have low resistance to electric current are called electric conductors. Many metals-including copper, aluminum, and steel-are good conductors of electricity. The outer electrons of metal atoms are loosely bound and free to move, allowing electric current to flow.
