Conductor and Isolator – In this discussion, Yuksinau.co.id will discuss in detail and in detail about Conductor and Insulator Materials. Where will we review starting from understanding, properties, materials/objects, characteristics, and examples of conductors and insulators.

Definition of Conductor

What is a conductor? A conductor is a substance that can conduct or as a conductor of heat and electric current. Good in liquid form, solid, or gas.

This is because the object or a substance has conductive properties. Conductors have a relatively small type of resistance system. This resistance is due to the materials used, that is, from the size of the material, and also the resistance is inversely proportional to its cross-sectional area. An example of this conductor is copper, iron, zink/seng, it's not, and many other types of metal.

The definition of a conductor and an example of this conductor can be observed on a copper wire. Where the thicker the copper wire, the lower the copper resistance.

The copper resistance was inversely proportional to the large cross-sectional area. As was the case earlier, long copper wire has a high resistance compared to short copper wire.

Conductor Properties

Following are the properties of conducting materials:. What are they? here's the explanation :

Essential ingredients that have important properties :
a. Heat conduction
b. Electrical conductivity
c. Resistance temperature coefficient
d. Tensile stress strength
e. The emergence of thermo-electro power

Heat Dissipation

Heat Transfer Power This property is a condition that can express the amount of heat that passes through the material layer in a certain time. Materials or objects that have high heat conductivity are metal objects.

And the heat conductivity was expressed in the form of kcal units / jam °C.

Electrical Conductivity

Current flowing in a conductor will experience resistance from the conductor. The magnitude of the resistance depends on the type of material.

The magnitude of the resistance per meter with the cross-sectional area 1 cubic millimeter at temperature 20 °C is called the resistivity. The amount of resistivity of a material can be calculated using the following equation: :

R = ρl/A

Information :
R : Barriers to delivery, unit ohm (Ω)
ρ : Material type barrier, in units Ω.mm2/m
l : Sender length, the unit is meters (m)
A : Cross-sectional area of ​​the conductor wire, mm unit²

Pressure Temperature Coefficient

In a material will experience a change in volume when there is a change in temperature. The material will expand when the temperature rises and will shrink when the temperature decreases.

Large resistance changes due to temperature changes can be known by the following equation: :

R – R0 ( 1+α (t – t0)

Information :
R : Great resistance after temperature change
R0 : Big initial resistance, before temperature change
T : temperature temperature (end), in °C
T0 : temperature temperature (early), in °C

Thermo Electro Power

Thermo Electro Power The electric current in the electric circuit will always change at each thermo electro-motor power, this is when there is a change in temperature conditions.

This property has an important role in 2 different types of metal which are attached to 2 contact point. Electro-thermo power is electro-motor power to be used in different temperature conditions.

The temperature difference was directly proportional to the two materials produced, and there is a big difference in each electric voltage.

Tensile Strength

Tensile Stress Strength This property plays a very important role as well, which is used when high stress distribution occurs.

Resistance Temperature Coefficient

The material will expand when it is at a high temperature, and will shrink when the temperature decreases. The most commonly used conductor material is copper, because copper is easy to get.

Definition of Insulator

An insulator is a material that cannot or in other words it is difficult to move (payload) electricity. Generally, an insulator is a barrier to the flow of electricity.

Another function of the insulator is to support the load or act as a separator between conductors by not allowing current to flow outward or between conductors..

This tool is also often used as a tool used to support power transmission cables which are usually found on power poles.

There is nothing perfect for this insulating material, this is because the insulator carries a small amount of mobile charge or in simpler words, it is still a charge carrier that can be carried when an electric current flows.

This is what makes the insulator electrically conductive when using a large enough voltage, so that the electric field will flow or channel water from the atom, which is known as the Breakdown Isolator.
