Which of the following accurately describes what makes a material a good conductor?

Which of the following accurately describes what makes a material a good conductor?

When discussing what makes a material a good conductor you say, “They must resist neutron flow.” readily accept electron flow.” readily accept neutron flow.” resist electron flow.” If you are looking for a material that is a good conductor, you will look for a material that will (2 points) readily accept neutron flow.

Which of the following accurately describes a property of an insulator?

An insulator is a bad conductor of electricity because it doesn’t allow the flow of electrons. So, the correct option is that an insulator has a property that it inhibits the flow of electrons.

What is insulator and its properties?

An insulator is a solid material whose inner electric charge does not drift freely, and therefore which does not conduct current under the impact of an electric field. Insulators are non-conducting materials. I.e. it resists electricity. It has great resistance value, usually in Mega ohms.

What are the properties insulator should possess?

Insulators have very high resistivity. For example, insulators like glass have a resistivity value as high as 1012 Ωm. The resistance of the insulator is considerably reduced in the presence of moisture and when there is an increase in temperature. Property 3: Insulators have large dielectric strength.

What are the 3 characteristics of an insulator?

The Properties of Insulators

• High Resistance. The ability to impede electric current from passing through is known as electrical resistance; this property is measured in units called ohms.
• Breakdown Voltage. All insulators will conduct heat and electricity if subjected to extremely high voltages.
• Atomic Structure of Insulators.
• Air Permeability.

What are the fundamental properties of insulating materials?

The insulating material should have the following properties.

• The material must have high mechanical strength so that it carries the tension and weight of the conductors.
• They must have high dielectric strength.
• The material is highly resistive for preventing the flow of leakage current from the conductor to earth.

What are examples of insulating materials?

Insulation Materials There are two types of insulating materials: radiant barriers and reflective insulation systems. Some of the commonly used insulation materials in homes include the following: rock wool, slag wool cellulose, glass wool, polystyrene, urethane foam, vermiculite, perlite, wood fiber, and plant fiber.

How many classes of insulating materials are there?

7

Is pure water an insulator?

Well actually, pure water is an excellent insulator and does not conduct electricity. The thing is, you won’t find any pure water in nature, so don’t mix electricity and water.

Is salt water an insulator or conductor?

This is because salt water is a good conductor of electricity which makes ocean water a resource for renewable energy. Salt molecules are made of sodium ions and chlorine ions. When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely.

Is water a good heat insulator?

Water has a high specific heat capacity. Specific heat capacity is defined as the amount of energy it takes to raise 1 ml of a substance by 1 degree Celsius. Since water is high, it take a large amount of energy to raise its temperature. That is why it is a good insulator.

Why is distilled water an insulator?

Distilled water is a good insulator because it is a good ionic solvent which allows them to dissolve ionic compounds easily without any hassle. Since it contains a large number of dissolved ions it cannot become a good conductor of electricity.

Why is distilled water an insulator Class 8?

Distilled water does not conduct electricity as there are no ions present in it. It can be made into a conductor by adding a small quantity of impurity, e.g. salt. There are no ions present in it.

How is pure distilled water an insulator?

Pure, distilled water is a very good insulator at relatively low voltages, even 110V AC. Tap water can be a good conductor due to calcium, magnesium, and carbonate ions, or other substances. But distilled water has no additional ions, except for H+ and OH-. The bottom line is that water itself is a poor conductor.

Is silver nitrate a good conductor of electricity?

(c) Both solid silver (Ag) and molten Ag are good conductors of electricity. However, solid silver nitrate, AgNO3, is a good conductor only when melted or dissolved in pure water; as a solid, it is a poor conductor. Therefore migration of outer electrons doe not occur, and no conductivity is detected in the solid form.

Why is agno3 a poor conductor?

Answer. it is because silver nitrate is an ionic compound and this it’s molecules are tightly packed with each other ans thus can’t carry charge.

Can C6H12O6 conduct electricity?

Copper conducts electricity, while sugar, C6H12O6, does not.

How do you know if something is conductive?

The easiest way to determine whether a compound can conduct a current is to identify its molecular structure or composition. Compounds with strong conductivity dissociate completely into charged atoms or molecules, or ions, when dissolved in water. These ions can move and carry a current effectively.

How do you test if a material is a conductor or insulator?

Try it this way: Touch the open ends of the two wires to each other to form a circuit and test the bulb. Touch the two open ends of the wire to each material you are testing, one at a time. If the bulb lights up, it is a good conductor. If it doesn’t, it is a good insulator.

How do you test if materials conduct electricity?

1. Connect the positive side of your power pack to the bulb holder and another wire to the other side of the bulb holder. Your conductivity tester is now ready to be used. (
2. Gather different household items to determine if they conduct electricity.
3. Touch the ends of wires to the different objects.

How can you test if materials conduct electricity?

Calculate the electrical conductivity from the resistance, length and area of the current. The resistivity is given as p = RA/l where p is the resistivity, R is the resistance, A is the area and l is the length. The conductivity is s = 1/p where s is the conductivity.

What kinds of materials can electricity not pass through?

Materials that do not allow electricity to pass easily through them are called insulators. Rubber, glass, plastic, and cloth are poor conductors of electricity. This is why electrical wires are covered in rubber, plastic, or cloth. Electricians even wear rubber gloves when they are working with electrical wires.
