Which of the following is composed of two conductors separated by an insulator?
A capacitor is a system of two conductors separated by an insulating (dielectric) material. When equal and opposite charges are on the conductors, the capacitor is said to be charged.
Is composed of two conductive plates separated by an insulating dielectric?

What are the uses of insulators?
Insulators work as protectors. They may protect heat, sound and the passage of electricity. Thermal insulators, sound insulators and electrical insulators are used for various reasons, from keeping houses warm to protecting electrical wires and soundproofing rooms.
What are 3 ways you use insulators in your everyday life?
Thermal insulators, sound insulators and electrical insulators are used for various reasons, from keeping houses warm to protecting electrical wires and soundproofing rooms….The most effective electrical insulators are:
- Rubber.
- Glass.
- Pure water.
- Oil.
- Air.
- Diamond.
- Dry wood.
- Dry cotton.
What are the types of insulators?
A look at some types of insulators and the conditions under which they are deployed.
- Pin-type insulators.
- Line post insulators.
- Suspension insulators.
- Strain insulators.
- Shackle insulators.
- Post insulators.
- Cap and pin insulators.

What are the two purpose of insulation?
Insulation in your home provides resistance to heat flow and lowers your heating and cooling costs. Properly insulating your home not only reduces heating and cooling costs, but also improves comfort.
What is important for insulation?
Insulation will help you keep the desired temperature in your house all year round, protecting it against cold in winter and excess heat in summer. Insulation is also useful to reduce noise pollution. A well-insulated house is very energy efficient and will need very little additional heating and cooling.
What is the significance of insulation coordination?
Insulation coordination is the process of selecting the most cost-effective equipment dielectric strength and its application to avoid equipment insulation damage or affect continuity of service.
Why is cotton a bad insulator?
It is often said that cotton is a poor insulator when wet because the fibers collapse when they get wet, eliminating the dead air space which provides the insulation.
