Because electrons will not flow through rubber.
It's there to protect you from getting electrocuted
Electrical wires are covered with rubber because rubber is an insulator.
The (plastic) or rubber or whatever is covering a wire acts as an insulator to keep the metal parts (the conductor) of the wire from touching each other (which would cause a s…hort circuit and possibly a fire) and from touching you when energized (which could cause a nasty shock.)
Electrical wires have plastic covering as when electric current flows through the copper wires and mistake we hold it so we may get an electric shock.
Answer The rubber or plastic serves as electrical insulation (because they are poor conductors). Without insulation, the electricity running in a bare cable would leap over i…nto any other electrically conducting material it touched. With enough voltage, a human could be electrocuted. Electrical signals would disappear and get lost, causing equipment to fail. Answer So the conductor is insulated against possible metal contact & prevent a short if it's grounded. Answer All household electric wires are covered with plastic and rubber. This is called insulation. It keeps the potential of the wire from returning to ground (short circuit) before being used by the load. The higher the potential (voltage) the greater the insulation factor has to be. Bare wires in transmission towers also use insulation in the form of air. To use this method, engineered clearances have to be maintained between the conductors. Answer All electrical power wires are covered with an insulating material. This is to prevent the potential on the wire from going anywhere except to the load. Electrical connecting wires are covered with plastic to prevent the wire under the covering from shorting out against each other or shorting out to ground. The electrical terminology for this covering is the wire's "insulation". These days most electrical wires are covered with a flexible plastic (rubber starts with the sap from a rubber tree; plastic usually starts with a petroleum base). Answer The main purpose of the "cover" (insulation) is to keep the wire from shorting to other objects. The plastics used generally have a good mix of the following properties: It is flexible so the wire can be flexed and bent. It is inexpensive and easy to apply to the wire during manufacturing. It has resistance to chemicals and UV light. Sometimes it's also important for it to resist abrasion or temperature extremes, or submersion in water. You can get wire with different types of insulation depending on what you need it to withstand.
Because metal conducts heat so it get hot, therefore it is cover with plastic/rubber (which don't conduct heat) to stop you burning yourself! :)
No, you can not because the plastic or rubber keeps the electrical charges from rubbing together.
The electrical copper wires are coated in rubber or plastic to ensure that no current is diverted away from where it is intended to go. As rubber and plastics make very good i…nsulators, as well as being cheap, easy to apply and flexible, it ensures that the electricity wont be conducted away from the circuit when in close proximity to another wire or any other conducting surface (or someones hands).
Plastic is used as it is flexible, but is an insulator (poor conductor of electricity), so the current runs down the wire and does not get transferred to anything else. It's d…ifferent colours, so that the wire function can be easily identified. In simple circuits, it's either a positive, negative or earth wire, but in more complex circuits with wires carrying signals, you get lots of different colours. It's really just so you can tell which wire does what - they are generally similar underneath the plastic, but they are connected to different things in specific ways, so you need to be able to see where a wire has come from and is going to.
yes Polyvinyl Chloride (PVC), and rubber are both good insulator's
Because rubber does not conduct electricity
It is because the rubber is an insulator.people don't get electric shocks that's why wires are covered with the rubber
