Question

The material through which electric charge can flow easily is
(a) quartz
(b) mica
(c) germanium
(d) copper

Answer 1

Answer ⇒ Option (d). Copper. 

The material through which electric charge can flow easily is  Copper (Cu). 

Explanation ⇒  Copper is the metals which is one of the good conductors of the heat and the electricity. It allows the Electricity (or Electric Charge) to flow through it without giving much resistance.

 The electrons in the metals are free,whereas in the non-metals they are not free. Therefore metals gives low or zero resistance and allows the electric charge to flow through them.  

Almost all the pure metals allows the Electric charge to flow through them, i.e. are the good conductors of the Electricity. Therefore they have the wide applications in the fields of the Electrical Industry. 

Copper along with the Aluminium is the highly conductive metals than the others metals. Thus they are mostly used in the Electrical Industry. 

Hence, Option (d). Copper (Cu) is correct.


Hope it helps.
