No, practically all plastic is an insulator. An insulator does not carry any electrical currents. A conductor can carry a current.

(most)Plastics are excellent electrical insulators, which protects people, and other wires from electric current.

Why do electrical wires have plastic covering?
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.
Explain why the outside cases of electric appliances ususally are made of plastic?
Plastic is a good insulator and a bad conductor of electricity, which makes it a good material to protect people from electric shocks when handling appliances. On top of that, plastics are inexpensive and easy to shape.
What is a device that protects an electric network by automatically opening a circuit when the current grows too strong?
Circuit breakers and fuses are both devices that protect an electric network byautomatically opening a circuit when the current exceeds a predetermined level.
What is a devices that protect electronic equipment from variations in electric current?
A fuse is designed to 'blow' if the incoming current exceeds its rating. A rectifier circuit will 'clean up' spikes in the mains supply.
What does this sentence mean fuses are the police officers of electric current?
Fuses protect an electrical circuit. When current in an electrical circuit becomes dangerously high the fuse will open protecting people and property. Police men/women protect people and property from the dregs of society.
Homeowners buy surge protectors to protect their possessions from unexpected surges of what?
Electric Current
Why electrical wires have plastic covering?
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.
A material which an electric current does not pass by easily?
An insulator. (plastic, glass, porcelain, wood, rubber...)
Why do electrical wires have plastic covering?
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.
What does covering a saucepan handle with plastic help to prevent?
It prevents the conduction of heat or even conduction of electric current shock in electric saucepan.
What is meany by resistor?
Resistor is a component of an electric circuit that resist the flow of direct or alternating electric current . It can also limit or divide the current, reduce the voltage, protect an electric circuit, or provide large amounts of heat or light.
Are all electric wires in a house metal?
Yes. Conducting carbon and plastic cannot cope with the current.
why do circuits need fuses?
Any electric circuit need to be equipped with electric fuses to protect the electric appliances or any electric/electronic equipment from damage due to unexpected electric current sudden or transient increase.
Explain why the outside cases of electric appliances ususally are made of plastic?
Plastic is a good insulator and a bad conductor of electricity, which makes it a good material to protect people from electric shocks when handling appliances. On top of that, plastics are inexpensive and easy to shape.
What is an advantage of wrapping wires in plastic rather than paper or cloth?
Plastic is durable and will ensure that electric current does not pose a threat to anyone. Papers may get torn thus leaving the wires exposed. A piece of cloth can also get wet and become a hazard as it will allow electric current to flow through it.
Which of these materials would not be a good insulator of electricity?
An example of a good insulator of electricity would be rubber. An insulator is anything that does not conduct electricity and as such offers protection from direct electric current.
What is a device that protects an electric network by automatically opening a circuit when the current grows too strong?
Circuit breakers and fuses are both devices that protect an electric network byautomatically opening a circuit when the current exceeds a predetermined level.
