Isolator objects: definition and examples

Insulator objects. (Pixabay)

YOGYAKARTA - What are the objects that are classified as insulators and conductors? As we learned in elementary school, the properties of objects can be divided into two types, namely objects that easily conduct heat and objects that dampen heat. Both types of objects are called conductors and insulators. So what are the objects of insulators and conductors? Check out the full review below.

A conductor is a material that is capable of conducting heat or electric current, either in liquid, solid, or gas form. An insulator is a type of material that is not capable of conducting heat and is also not capable of conducting electric current.

Isolators are also referred to as current barriers. This material can also be used to limit conductors and is also able to function as a load support. As for examples of objects that are included as conductors and insulators, we will discuss below.

Examples of Isolating Objects

What are examples of insulator objects? Here are examples of insulator objects around us:

Panci Handle and Ironing Board Handle

Quoted from the book Arif Cerdas untuk Sekolah Dasar Kelas 5 by Christiana Umi (2020), the handles of the pot and the iron set are included as insulators because they consist of plastic and wood materials. Both materials have slow properties to conduct heat.

Cotton

Dry cotton is an excellent insulation material. Usually this object is used in cloth tape to protect electrical wires and prevent people from being electrocuted.

However, if the cotton is wet, the cotton is no longer an effective insulator and, on the contrary, can become an electrical conductor.

Paper

The natural cellulose contained in paper makes it a strong electrical insulator. Many early electric machines were made with paper boards or pressboards, which were made with many layers of dried paper.

Later, electrical and telephone cables were often insulated with thick paper, although many companies used these cables with plastic insulation.

Sodet

In general, the sodet is made from wood and plastic materials that are resistant to heat. Therefore, the handle of the sodet is an example of an insulator.

Termos

The glass wall inside the thermos has the benefit of being a conductor. Meanwhile, glass cannot absorb heat or reflect it back. Thus, the temperature of the water inside will not spread out. That's why we don't feel hot when our palms hold the thermos.

Gloves/Hand Protectors

Gloves are made from fabric materials that have insulating properties. Therefore, this material can inhibit heat.

Example of a Conductor

Besides knowing examples of insulating objects, it is also important for us to know examples of conducting objects, among others:

Ironing

The iron base is made from iron material that is able to transmit heat from electricity to clothes.

Panci

The pot is a conductive object because it can transmit heat from the fire to the oil, water, or food being cooked.

Hair Straightener

Tools used for beauty include examples of conductive objects because they are able to conduct heat from electricity.

Close the Panci

Close the pan made of glass including conductive materials. However, glass is not as good as metal in conducting heat.
