Your question: Can the electric wires at home be covered with aluminium foil instead of plastic Why?

The covering of an electric wire is made of plastic because plastic is an insulator, which does not allow current to flow through it. … If instead of plastic the wire is covered with aluminium foil, it can be dangerous as the aluminium foil is a conductor and can conduct electricity and lead to shocks.

Can the electric wires at home be covered with Aluminium foil instead of plastic?

No , we can not use aluminium foil to cover the wires at home because aluminium is good conductor of heat and electricity.

Can electric wires be covered with Aluminium foil instead of rubber give reasons to support your answer?

No, it can’t be covered with aluminum foil as aluminium is a conductor of electricity and we may get electric shock whereas plastic is a bad conductor of electricity so it is used to cover wires.

Can aluminum foil be used as a wire?

100 mA into a strip of heavy duty kitchen aluminum foil, width a few millimeters, driven by a AA battery will be just fine. If some part of the foil is too thin and generates too much heat because you’re drawing amps’ worth of current, the foil will act like a fuse and burn off.

Why are electric wires used at home covered with plastic?

Covering electrical wiring using plastic ensures that the current doesn’t flow outside the system. This avoids shocks, short-circuit etc. … Plastics are non-reactive and poor conductors of electricity or to be precise, they are insulators. They do not allow the electric current to pass through them easily.

Which side of aluminum foil is more conductive?

I assume you mean, “On which side would electrical contacts to the foil have lower resistance?” The conductivity is through the bulk of the material (ignoring high-frequency skin effects, etc). You would get better contact to the shiny side. The shiny side is shiny because it is smooth.

Is Aluminium good conductor of electricity?

Aluminum. Aluminum is yet another metal known for its high conductivity of electricity. Though by volume its conductivity is only 60% of copper, by weight, one pound of aluminum has the electrical current-carrying capacity of two pounds of copper. … Aluminum is often used in satellite dishes.

Is aluminum foil a good insulator?

Aluminum foil can be an effective insulating material because it doesn’t radiate heat out into the environment. That’s what makes it effective directly under a roof: although it will warm up through conduction from the shingles, it won’t radiate that heat out into the attic space.

What are electric wires covered with rubber or plastic?

Most electrical wire is covered in a rubber or plastic coating called insulation.

What metal is used in wires around the house?

In the case of household wiring, the conductor itself is usually copper or aluminum (or copper-sheathed aluminum) and is either a solid metal conductor or stranded wire. Most wires in a home are insulated, meaning they are wrapped in a nonconductive plastic coating.

Why are electric wires coated with PVC?

Complete answer:

PVC is an insulator, so wires are coated with it to keep us from getting electric shocks. Electric wires are made of metals that conduct electricity, such as copper, but they are coated with rubber. As a result, it’s an excellent material for electrical applications like cable insulation sheathing.
