Electricity is not "captured" inside of electrical wires. The question makes no sense.
which electrical wires bring electricity to an electrical device or motor The cable, otherwise known as the flex or the lead.
electricity moving on wires
An insulator is a material that prevents the passage of electricity. An example is the plastic insulating cover on electrical wires, A conductor is a material that allows electricity to flow. An example is the copper wire used inside electrical cables.
Electrical wires are made from copper, as copper is a good conductor of electricity.
cell phones use electricity by the electrical wires outside
There are three! (i think)
Electricity is the energy that flows along wires. It is the movement of electrons through a conductor, such as copper wires, that allows electrical devices to operate.
Negative charge
To allow the wires to be connected to a source of electricity.
Yea it is! That is why most of electrical wires are made of Copper!
The material that is often used to insulate wires that conduct electricity is called electrical insulation. This material helps prevent the flow of electricity between the wires and protects them from damage or short circuits. Common materials used for electrical insulation include rubber, plastic, and fiberglass.
The most common electrical insulator is the plastic coating on electrical wires. Hope this helps!
