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.
A material through which electric current does not pass easily?
An insulator is a material that hinders the flow of electric current due to its high resistance. Examples include rubber, plastic, and glass. Insulators are commonly used to protect against electrical shocks and to prevent short circuits.
What a material that current can't pass through easily?
One material that current can't pass through easily is an insulator, such as rubber, plastic, or glass. These materials have high resistance and do not allow electric current to flow freely. Insulators are used to prevent electric shock and protect electrical circuits from unwanted interference.
A material that current does not easily flow through?
An insulator, such as rubber or plastic, is a material that current does not easily flow through because it has high resistance. These materials have tightly bound electrons that restrict the flow of electric current. Insulators are commonly used to protect against electric shocks and to prevent short circuits in electrical systems.
What type of material will you find all the way around the outside of an electric circuit to protect it?
The material that surrounds the outside of an electric circuit to protect it is typically an insulating material, such as plastic or rubber. This insulation helps to prevent electrical shock and short circuits by keeping the current confined within the circuit.
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.
What do the insulators have in common?
Insulators are materials that resist the flow of electric current. They have high electrical resistance and are used to prevent the loss of energy through heat and to protect against electric shocks. Common insulating materials include rubber, glass, plastic, and porcelain.
What do you call a material that wont carry an electric current?
An insulator is a material that does not conduct electricity and will not carry an electric current. Examples of insulators include rubber, plastic, and glass.
A material which an electric current does not pass by easily?
An insulator. (plastic, glass, porcelain, wood, rubber...)
What can stick to a magnet but doesn't conduct electricity?
A material like plastic can stick to a magnet but does not conduct electricity. This is because plastic is an insulator and does not allow electric current to flow through it.
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 material has high resistance to the flow of electric current?
The material that has high resistance to the flow of electric current is called an insulator. Examples of insulating materials include rubber, glass, and plastic.
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.
