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.
Which property makes it difficult for electricity to pass through a material?
density
What do you call materials that can pass through electric?
Electrical Conductors.
