They are poor conductors of electricity. A few examples of insulators are erasers, paper, glass, and cotton. Insulating material made of glass or any other good insulator may be used in between electric wiring as a protective barrier and to prevent shock.

What does erasers mean?
Erasers are usually made of rubber, which is a pretty good insulator. Of course, at high enough voltages, everything is a conductor. Is a chalkboard eraser a conductor?
What is a insulator?
Insulators allow us to handle current-carrying wires, switches, plugs, sockets, and other electrical appliances safely. For example : The electric wires are covered with insulators like plastic or rubber. Being an insulator, plastic (or rubber) covering does not conduct electricity flowing through the wire into our body when we touch it.

Why do you wear rubber shoes?
This is because rubber is an insulator which will protect us from electric shocks in case there is a leakage of electric current from the appliances. Notes for Chapter 12 Electricity and Circuits. Electricty.
Why are conductors and insulators important?
Importance of Conductors and Insulators. Conductors are used to carry electricity (or electric current). Electricity is carried in our homes by copper wires or aluminium wires) because copper (and aluminium) are conductors of electricity. A person will get an electric shock if he touches a bare wire carrying electricity (or electric current).
What is the purpose of plastic insulation?
So, if we happen to touch a current-carrying wire covered properly with plastic (or rubber) insulation, we will not get an electric shock. Thus, the plastic (or rubber) covering on the wires protects us from the electricity that is flowing through the wire.The plastic insulation makes the electric wires safe to touch.
Why are wires made of copper?
Electric wires are made of copper and aluminium because they are conductors of electricity. For example : iron, steel, mercury, gold, metal alloys (like Steel, brass ,bronze) are conductors of electricity. All the objects made of metals or metal alloys are also conductors. The objects such as coins, keys ,pins, aluminium foil, ...
Why are electric plugs covered with plastic?
Electric plugs, electric switches, electric plugs, electric sockets, electric iron, toaster and ovens, etc., are also covered with insulator material like plastic to protect us from the electricity passing through them. (1) Those parts of an electrical component or appliance through which electric current has to pass, ...
What happens if you touch a wire?
So, if we happen to touch a current-carrying wire covered properly with plastic (or rubber) insulation, we will not get an electric shock. Thus, the plastic (or rubber) covering on the wires protects us from the electricity that is flowing through the wire.The plastic insulation makes the electric wires safe to touch.
Why do wet hands get electric shocks?
If a person operates an electric switch with wet hands ,he can get an electric shock because water present on the wet hands can conduct some electricity from the switch into his body. We should, therefore, operate the switches of electrical appliances with dry hands.
What is dip strip?
Dip Strip is used to chemically remove the insulation from virtually all magnet and enamel wires of all sizes and insulation types, without damage to the wire. When heated in the specially designed stripping pot, the Dip Strip melts and wires are immersed in the Dip Strip to strip the insulation.
What is a DSP stripping pot?
The DSP stripping pots are designed specifically for use with Dip Strip. The standard model DSP1 has an infinitely variable temperature control with a reference scale. Dip Strip is used to chemically remove the insulation from virtually all magnet and enamel wires of all sizes and insulation types, without damage to the wire. When heated in the specially designed stripping pot, the Dip Strip melts and wires are immersed in the Dip Strip to strip the insulation. The stripped wires are then rinsed in water and Dip Clean Metal Cleaner to remove oxides and residue. Dip Strip does not corrode conductors as will acid strippers.

What is a D series wheel stripper?
The D series wheel strippers cover many applications for stripping magnet, enamel and film insulated wires. Round, rectangular and square section wires with insulation such as Formvar, ML, Dayglass, Isonel, Polythermaleze and many more can be stripped.The DV1 has an integral dust collection system to trap insulation residue as it is removed from the wires during stripping. Fybrglass or wire brush wheels may be utilized with the DV1 to strip wires. Fybrglass wheels rotate at high speed and generate frictional heat that softens the insulation on the wire and the “nap” of the wheel wipes it away. A clean polished surface is produced with no risk of nicking. Wire brushes remove insulation by the cutting action of their many bristles. These are more abrasive than Fybrglass wheels and are recommended for larger wires where a roughened surface aids subsequent soldering. Wire brush wheels will also remove glass and fabric insulation. The selection of the correct grade of stripping wheel is critical.
What is a blade stripper?
Eraser blade strippers are great for round magnet and enamel wires with any type of film insulation, from solid and stranded wires and round cable and coax. Rotary strippers are the perfect machine if you need to cleanly remove insulation with no damage to the wire conductor. View Blade Strippers.
What is thermal wire stripper?
Available in a lightweight hand held model or a bench model, thermal wire strippers are perfect for stripping solid and stranded wires up to 1/2" OD. The HTS1C is especially effective on insulation such as P.T.F.E. and Teflon. The temperature at the stripping elements is variable up to 1400°F The bench model can be used for window stripping.

What is an eraser L4?
Eraser’s Model L4 Portable Rotary Insert Wire Stripper will remove film insulations including enamel, Formvar, ML, armored poly-thermaleze and epoxy from round wires. Model L4 can also be used for other applications such as; deflashing wires,cleaning legs of electronic components and cleaning pins on transformers and coils. A high-speed rotating insert strips insulation from the surface of the wire. Close-up stripping is possible flush to a coil body or bobbin.
What does a fiberglass wheel do?
Fiberglass wheels will strip many film type insulations. The conical wheels rotate at high speed to generate frictional heat which softens the insulation on the wire. The “nap” of the brush wipes this insulation away. Many of the machines work for square, rectangular, or flat magnet or enamel wire insulations including glass, varnish, epoxy and polythermaleze.

What are Conductors?
Conductors are substances that allow electricity to pass through them freely. The reason behind this is that these substances contain many atoms that have loosely bound outermost electrons or valence electrons.
What are the elements on the left of the periodic table?
The elements present in the left of the periodic table are non-metals and are mainly insulators. Substances which are largely made up of such elements are insulators. The insulating materials or elements have the valence electrons tightly bound. These electrons cannot be freed or loosened. They are poor conductors of electricity.
What is the opposite of a conductor?
Insulators are just the opposite of conductors. They are substances or materials that do not conduct electricity. Insulators inhibit the easy passage of electrons from atom to atom and thus do not allow electric current to pass through them.
What are some examples of insulators?
A few examples of insulators are erasers, paper, glass, and cotton. Insulating material made of glass or any other good insulator may be used in between electric wiring as a protective barrier and to prevent shock.
What are some examples of conductors of electricity?
Nails, safety pins, iron rods, etc, are a few examples of conductors of electricity. The human body is also a conductor of electricity. Thus, we need to be extra cautious that we do not get an electric shock. We need to take due precautions when dealing with electricity.
Where are metals found in the periodic table?
In an electric circuit, these electrons can freely move around the circuit with a domino-like effect. Metals are found towards the right of the periodic table.
Which metal is used in electrical wiring?
Can you name a metal which you are familiar with which is used in electrical wiring? Copper is the metal that is primarily used for electrical wiring because each copper atom has only one valence electron which can be easily freed. Thus, it can easily be harnessed in electricity as it is an excellent conductor.
