Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons.
Good insulators are materials that do not allow the flow of electrons (current). Examples are rubber plastic, nylon, glass, ceramic, rubber, dry wood, air.

∙ 14y agoThere is a large number of materials that do not conduct electricity or are poor conductors of electricity. They are referred to as insulators and dielectrics Glass for example is an excellent insulator, thus the old glass insulators that used to be used on power poles to support high voltage power lines. Many hydrocarbon compounds (plastics, etc.) are good insulators. I recommend you look up dielectric's on the web for more information.

What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
What is the difference between a electrical conductor and a electrical nonconductor?
Simply put an conductor is a material that lets free electrons flow through it. When free electrons are flowing that is called current. So an electrical conductor will have current pass through. Non-conductive material will not allow these electrons to flow and no electricity can be passed through. Good conductors have almost no resistance to electron flow.
What constitutes a complete electrical circuit?
A complete electrical circuit occurs when it is possible for electrical current to flow through the electrical devices in it.
Flow of electricity through a wire is called?
It is called electrical current.
The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
What materials will conduct the flow of electricity?
While electricity doesn't flow, current does. Conductors are materials that allow the electrical currents to flow through them. Metals are the best conduction, such as silver and copper.
What things are insulated?
An insulator is a material that does not allow electrical current to flow freely.some materials are better then other copper is the cheapest most effective per cost ratio conductor of electricity............( allows current to flow with relative ease) plastics glass ceramics all are poor conductors of electricity(electrical current doe not flow freely) there for can be used for insulation, for safety and control of electrical flow.
What does to allow energy of electricity to flow mean?
It means that you let an electrical current flow. The current will, of course, carry energy.
What item carries the most current?
A Super-conductor will allow the greatest flow of electrical current.
What kind of substances can electric current can flow through?
Elements, compounds, materials with high electrical conductivity.
Materials that electricity cannot flow through?
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. The main materials that do not allow the easy flow of electrons are rubber, nylon wood, glass, ceramic, plastic and free air.
What is a circuit which will allow flowing current?
As long as an electrical power source is connected to itself with electrical conductors of some kind, then a current will flow through it. How much current will depend on the components used in the circuit.
What does an electrical current flow in?
Electrical conductors.
What a good insulators?
Insulator is a material that resists the flow of electric current. materials such as glass, paper or Teflon are very good electrical insulators. These materials are used to support or separate electrical conductors without passing current through themselves.

What structural component of cardiac muscle cells allow for electrical current to flow from cell to cell?
The intercalated discs
