The resistance of a sample of a conducting substance is less than the
resistance of a physically identical sample of an insulating substance.
AnswerTo give you some idea of the difference between the resistance of insulators and conductors, a sample of mica (an insulator), just 25-mm long, has the same resistance as a copper conductor, having the same cross-sectional area, but measuring a staggering 14 290 000 000 000 000 000 kilometres long!To put this in perspective, the average distance from the Earth to the Sun is a mere 150 000 000 kilometres!

Is wood a conductor or an insulator of electricity?
Wood is an insulator.
Does plastic have a high resistance?
Yes, it has a high resistance as it is an insulator.
Is cotton wool a conductor of electricity or an insulator?
Cotton wool is not a conductor or an insulator it is a semi conductor. It is sort of in the middle, electrons can travel through cotton wool but not as good as silver, bronze, metal and so on.
Is glass a conductor or insulator of electricity?
Glass in a molten state is a conductor of electricity. When glass turns to a solid state it becomes an insulator.Basically, glass in a window or a test tube would be the solid state and so it is a insulator of electricity.
Is plastic wrapped around the electric wires is a good conductor?
Plastic wrapped around the wire is insulator. Not a conductor. That is why it is wrapped around the conductor wire.
Would a good conductor create more resistance or a good insulator?
Good conductor = low resistance.
Is a seashell a conductor or insulator?
A seashell is typically considered an insulator because it does not easily conduct electricity. The material of the seashell is not a good conductor of electricity due to its high resistance.
Can something be an insulator and a conductor?
No, a material cannot be both an insulator and a conductor at the same time. Insulators have high resistance to electrical flow, while conductors have low resistance.
Is vinyl a conductor or an insulator?
Vinyl is an insulator because it has high electrical resistance and does not conduct electricity easily.
Is a crayon a conductor or an insulator?
A crayon is an insulator. It does not conduct electricity well due to its high resistance.
What is the difference between conductor resistance and insulation resistance?
The resistance of a conductor is relatively low while an insulator should have very high resistance. The former is used to transmit electricity and the latter is designed to inhibit flow of electricity.
Is glass lens an insulator or conductor?
Glass is an insulator. It does not conduct electricity because it has high electrical resistance.
Is kerosene conductor or insulator?
its an insulator
Is a brick a conductor or an insulator?
A brick is an insulator. It does not conduct electricity well due to its high resistance to the flow of electric current.
Is concrete a conductor or a insulator?
Concrete is a poor conductor of electricity, so it is considered an insulator. Electricity does not flow easily through concrete due to its high resistance.
Is oxygen a insulator for a conductor of electricity?
Oxygen is not an insulator for a conductor of electricity. In fact, oxygen can facilitate corrosion in metals, which can affect their conductivity. Generally, the presence of oxygen can lead to increased resistance in conductors.
Is polystyrene a conductor or a insulator or a semi conductor?
Polystyrene is considered an insulator because it is a poor conductor of electricity. It has high resistance to the flow of electric current due to the lack of free-flowing electrons in its structure.
