as u know the voltage from the supply V=IR and for the electricity to pass through I=V/R so when R=∞ so I=0 , so the materials having very high resistance (R) is the materials that the electricity cant pass at the normal voltage which are called insulators usually non-metals like ( benzene , wood , paper , plastics , cotton , glass , ceramic , porcelain, ..... ) but for very high voltage happens surge at which this materials be conductors
normal voltage = 120 , 220
high voltage =120,000 220,000

Materials that allow electricity to pass through them also allow water to pass through them is this is right or wrong?
Wrong. Water will pass through paper but low voltage electrity will not. Electricity will pass through copper and other metals, but water will not. Water is a good conductor of electricity but so is steel and copper. However water will not pass through them unless they are in the form of tubing In the UK pipework (Gas and Water) in properties should be earthed to protect against electrocution.
What materials will not allow heat or electricity through?
electricity
Material that allows electricity to pass through?
Materials that allow electricity to pass through are said to be good conductors. Conductors have free electrons allow for the flow of charged particles through the material resulting in an electric charge. Most metals are considered to be good conductors, some examples include copper, aluminum, silver, and gold.
What do you call materials that can pass through electric?
Electrical Conductors.
Which property makes it difficult for electricity to pass through a material?
density
What are materials that do not let electricity pass through them called?
Insulators
What makes these materials be insulators?
Electricity is unable to pass through them
What are the materials that can let electricity pass through?
Generically they are called conductors.
What are not insulators?
Insulators are materials that don't conduct heat well, or (for electricity), materials that don't let electricity pass through them. In general they are non-metallic materials.
What materials allow heat to pass through and electricity?
metals have the ability to pass and conduct electricity and heat through them....
How are superconductors different from insulators?
Superconductors are materials that let current or electricity pass through them. Insulators are materials that don't allow current or electricity to pass through them. Superconductors are mostly all metals. Insulators are wood, plastic, and paper.
What is the difference between conduct and insulate?
Insulation is keeping the heat inside, trapping it and not letting out. Conduction is letting a flow, such as electricity, pass through the material. for example, metal is a wonderful conductor of heat and electricity, but a bad insulator. However, wool is a good insulator and a bad conductor. :) hope that helps!
Material that allows electricity to pass through it easily?
Metallic conductors such as copper, aluminum, silver and gold are some examples of materials through which heat and electricity can easily flow.
What materials allow electricity to pass through them?
All metals for example iron, copper, nickel. They are called conductors. Plastics and other elements do not, only metals. They allow electricity to pass through them because they have free electrons
What allows electricity to pass through it?
An object which is a conductor allows electricity to pass through it

Can heat and electricity pass through metals?
Yes, heat and electricity can pass through metals.
