A charged insulator can be discharged by passing it just above a flame because a flame has a cloud of ions above it. Even though the overall charge above the flame is neutral, a charged insulator will use up the ions that it needs and neutralize.

What makes an insulator insulate?

A material that insulates, especially a nonconductor of sound, heat, or electricity. A device that insulates another material or space from something. For instance glass is a good insulator from electricity. The electrons will not flow through glass. Cork is a good insulator from sound. Sound waves have a hard time passing through cork. Wood is a good insulator from heat.

Explain electrolysis of water with the help of diagram?

Electrolysis of water involves passing an electric current through water to break it into hydrogen and oxygen gases. The positive electrode (anode) attracts negatively charged hydroxide ions (OH-) and oxidizes them to form oxygen gas and water. The negative electrode (cathode) attracts positively charged hydrogen ions (H+) and reduces them to form hydrogen gas and water. This process occurs in an electrolytic cell with two compartments for the gases to collect separately.


What substances normally fail to cross cell membranes under any circumstances?

Large molecules such as proteins and polysaccharides typically do not cross cell membranes. Additionally, charged ions like sodium (Na+) and chloride (Cl-) may have difficulty passing through cell membranes due to their charge.


Does the Particle Model explain Refraction?

Yes, the Particle Model can explain refraction by considering light as a stream of particles (photons) that change speed and direction when passing through different mediums, causing the bending of light rays.

Is a winter glove a conductor or insulator?

a glove is an insulator. It is designed to stop the cold passing through.


What Explain why conductors and insulator produce?

Conductors conduct electricity because they have free electrons that can move easily, allowing electric current to flow through them. Insulators, on the other hand, do not have free electrons and prevent electric current from passing through them. This difference in electron mobility determines whether a material acts as a conductor or an insulator.


Is a CD case a insulator?

Yes, a CD case is typically made of plastic which is an insulator. Insulators do not conduct electricity well and are used to protect against electrical currents passing through.

How do electrical insulators help people?

The insulator I refer here is the insulation on the wiring and this helps any in not passing current through them


Is cork a conductor of heat?

Cork is actually a poor conductor of heat due to its low thermal conductivity. This makes it a great insulator, helping to keep cold or hot temperatures from easily passing through it.


What kind of insulator would stop conduction?

A material that is a good insulator, such as rubber, plastic, or glass, would stop conduction of electricity. These materials have high resistance to the flow of electrons, preventing electrical currents from passing through them.


Does a insulator let eletricity pass through?

No, an insulator does not allow electricity to pass through. Insulators have high resistance to the flow of electricity, which prevents the current from passing through them. Examples of insulators include rubber, plastic, and glass.


What objects block heat and electricity from passing through?
