Question

to prevent short-circuiting and electrical shocks, the metallic wires carrying electricity are covered with

A. copper
B. aluminium
C. cotton
D. any insulator

plz ans as soon as possible

Answer 1

In order to prevent short circuiting and electrical shocks, the metallic wires carrying electricity are covered with any insulator.

• Insulators are certain materials having high resistivity and extremely low conductivity.

• Hence , resistance of this kind of materials is very high.

• Also , the charge carriers like electrons are tightly bound to the atoms.

• Presence of such stationary electrons make it very difficult for current to flow through this kind of materials.

Hence , they prevent any kind of shock.

Answer 2

The metallic wires carrying electricity are covered with any insulator to prevent short-circuiting and electrical shocks.

Explanation:

• An insulator is a thing through which it does not allows the electricity to enter into it.

• Current does not passes through things like paper, plastic and rubber and so they are used as the insulating materials to prevent us from electric shocks.

• We are covering the conducting materials with these insulating materials to prevent the electric current to pass through it and so these insulating materials are used  to cover electrical cables.
