So the solution is must be a solution of neutral electrolyte. For example NaCl is a neutral electrolyte which has no effect on litmus paper and the solution of NaCl conduct electricity as NaCl ionises to its constituent ions. Aakash EduTech Pvt.

Aluminum is a good conductor because it is a metal. In metals, the valence electrons are already detached due to the metallic bonds between atoms. We call these electrons that break the bond with their atom free electrons. They easily start moving whenever charge is applied to the metal.

Aluminum foil, also called tin foil, makes an excellent insulator, and in some situations, it works better than materials like cotton or paper.

Non-metals are generally bad conductors or insulators. Metals, on the other hand, are good conductors. Some other examples of poor conductors of electricity are mica, paper, wood, glass, rubber, Teflon, etc. Some examples of poor conductors of heat are air, lead, etc.

Sand is a solid and a poor conductor of heat. That means that when sunlight hits sand, all the energy of the sunlight is absorbed in the first millimeter or so of the sand, the heat stays there or spreads only a few millimeters down. So those few millimeters get quite hot.

The poorest conductor of heat among metals is Bismuth. Stainless steel is another one that is a poor conductor of heat, and you use this often in everyday life! Other poor conductors include titanium, lead and chromium. And most ironically, Mercury, the liquid metal used in thermometers!

Materials like glass and plastic are poor electrical conductors, and are called insulators. They are used to stop electricity from flowing where it is not needed or where it can be dangerous, such as through our bodies.

Conductors are materials that permit electrons to flow freely from particle to particle. Conductors allow for charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.

Most metals are considered to be good conductors of electrical current. Copper is just one of the more popular materials that is used for conductors. Other materials that are sometimes used as conductors are silver, gold, and aluminum. Aluminum and most other metals do not conduct electricity quite as good as copper.

So,In the normal or neutral conditions,the conductors are not harmful at all. But,when the conductor is conducting some amount of heat energy or electrical energy then the physical contact with the conductor might cause electrocution or burning.

Electrical safety tips for kids

• Never put fingers or other objects in an outlet.
• Keep metal objects out of toasters.
• Never use anything with a cord or plug around water.
• Never pull a plug out by its cord.
• Stay away from substations and power lines.
• Don’t climb on power poles.
• Never fly kites near power lines.

Conductors allow electricity to flow through them freely. Metals like copper are excellent conductors. Paper, on the other hand, resists the flow of electricity, so it typically acts like an insulator (paper is flammable though, so it’s not a very safe insulator.

There are three main types of electrical hazards: electric shock, electrical burns, and arc blasts (the effect of blasts).

A hazard is something that can cause harm, e.g. electricity, chemicals, working up a ladder, noise, a keyboard, a bully at work, stress, etc. A risk is the chance, high or low, that any hazard will actually cause somebody harm. For example, working alone away from your office can be a hazard.

The major hazards associated with electricity are electrical shock and fire.
