Is plastic wrapped around the electric wires is a good conductor?

Plastic wrapped around the wire is insulator. Not a conductor. That is why it is wrapped around the conductor wire.

What happens when there is no plastic coating on a electrical wire?
Nothing happens. The wire will still conduct electricity. An example of this is the overhead utility wiring. The insulation on a conductor is there strictly to keep the conductor from touching any thing that would ground the conductor. This grounding could be from another adjacent conductor or a grounded medium around the conductor. A grounded conductor will trip the over current protection and trip the circuit off line. Without an insulation on the wire multiple wires in a conduit could not be utilized.
What would happen if electric cords did not have plastic around them?
The plastic is a form of insulation. Insulation used to be made from non-plastic materials like cloth. It protects the wire from the outside world. Without insulation the electricity would cause shocks, fires, and short circuits.
How do current clamp on amp meters work?
clamp is an electrical device having two jaws which open to allow clamping around an electrical conductor. This allows properties of the electric current in the conductor to be measured, without having to make physical contact with it, or to disconnect it for insertion through the probe.
Can a wire be wrapped around a screw clockwise or counter clockwise?
Well, it CAN be wrapped either way, but because standard screws tighten when turned clockwise:if the wire is wrapped around the screw clockwise tightening the screw will pull the wire tighter around the screwif the wire is wrapped around the screw counterclockwise tightening the screw will push the wire away from the screw making it loose and maybe even popping the wire out from under the screwSo, if you want the wire to stay secure on the screw only wrap it clockwise!
What is formed around a conductor when a current is passed through it?
A magnetic field.
How are the conductors and insulators in the creation of household electric wire?
Copper is ideally used in wires in the creation of a household electric wire. this is because, copper is a very good conductor of electricity. to avoid anyone from getting shocks the copper wires need to be insulated by an insulating material, ideally plastic that is wrapped around them.
What is the magnet formed by the flow of electric current?
When electric current flows, a magnetic field is formed via induction. When copper wire, or another conductor is wrapped around a metal core, it forms an electromagnet.
What does Vince have wrapped around his head?
Plastic cone

Plastic is wrapped around live wire to prevent electrocution. why is plastic used to cover electrical wires?
You more or less just answered your own question. Most plastics are not good conductors, so the best path to ground for the electricity flowing in the wire is to stay in the wire rather than jumping through the plastic (poor conductor) and person (middling-to-fair conductor).
What other material could you place around the electric cords that can be as effective as the plastic?
Electrical tape and any non-conductor material such wood or plywood guard, glass and rubber.
Created around a conductor when electrons flow through that conductor?
Then an 'electrical current' is said to be present in the conductor.
Why would an electric wire be covered with an insulatos such as plastic?
Plastic being nonconducting, it avoids electrocution when covered around electric wire.
When an electric current is run through wires wrapped around an iron core creates what?
Electromagnetism
What is the best material to wrap hot food in?
Clean, unused aluminum foil can be wrapped around the food directly, or it can be wrapped around a plastic or glass container that the food is in (depending on the consistency of the food).
Why is the outside of an electrical cable made of plastic?
Cases have been made of wood, various metals, plastic, bakelite, fiberglass, and perhaps others. Plastic is widely used now primarily because of its low cost and ease of forming complex shapes.
How electric current causes magnetic field around conductor?
Electric current causes magnetic field around conductor by producing a moving electric charges and the intrinsic magnetic moments of an elementary particles that is associated with a fundamental quantum property.
