Copper wires are usually covered with rubber or plastics to prevent shocks and ensure safety. Because plastics and rubbers are insulators of electricity i.e. they cannot conduct electricity.
Why are wires usually covered with plastic or rubber?
Wires used in homes are usually covered with materials like plastic or rubber, because plastic and rubber are bad conductors of electricity and do not allow current to flow. This prevents us from getting a shock due to a short circuit.
What is the purpose of the rubber coating on wires?
The rubber coating on wires and cables prevents electric shock and provides a degree of protection from crimping or other damage. The insulation material may become nicked or cut.
What do you think will happen if there is no plastic or rubber that covers the wire?
Answer: Without plastic, hot and neutral wires cannot be run in the same conductor or same wire. another means would have to be developed to convey electricity safely to electrical devices. This would cause a great deal of hardship as well as consume a lot of finances to do it safely.
What are the household electric wires covered with plastic or rubber?
The electrical wires are covered with plastic coverings because the plastic is an insulator and thus it protects us from getting shocks.
Why are electric wires coated with PVC or rubber like material?
PVC is an insulator so to prevent us from getting electric shocks wires are coated with PVC. Electric wires are made of conducting materials like copper, but their coating is done with the help of rubber. it is therefore the excellent material to use for electrical applications such as insulation sheathing for cables.
Why are electric wires covered with plastic Class 6?
Electrical wiring is usually covered with layer of plastic to make it safe. As we know that plastic is an electrical insulator and it is readily available and cheap. So as to insulate the electricity carrying wire, to make it shock free.
Why are electric wires coated with such substances Class 10?
Ans: Electric wires are made up of materials like copper that are good conductors of electricity. To get rid of this conduction of electricity from these wires and cables, they are coated with insulating materials like PVC (Polymer) .
Is rubber a conductor?
Rubber itself usually cannot conduct electricity without any assistance. Rubber are poor conductors of electricity hence the reason you see electricians wear rubber gloves when they are working with electric wires.
Which is not a part of electrical circuit?
Current is not a part of a circuit.
A circuit may or may not have a current. The circuit essentially consists of a battery. The electrode of the battery has connecting wire connected to it.
