In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions.Materials made of metal are common electrical conductors. All good conductor of electricity wholesalers & good conductor of electricity manufacturers come from members. For example, the carbon in the form of graphite is a very good conductor of electricity. Distilled water - apparently water doesn’t conduct unless there are impurities in it. Median response time is 34 minutes and may be longer for new subjects. Give reason. Think of that 8-ball again: when it hits one ball, it knocks it farther than if it gently bumps into multiple balls. The material which do not allow electric current to pass through them easily are called poor conductor of electricity.. Here is a lowdown of why wood could be a conductor or an insulator. There are some non - metals which are a very good conductor of electricity. These include air, glass, wood, plastic and rubber. Pure water or distilled water is a poor conductor of electricity. Slipped disc | woman conductors: the power list. how_to_reg Follow . Uranium is a metal and is a good conductor of both heat and electricity. However, there are people who push the idea that wood is a good conductor because of some of its natural properties. Semi-conductor metals have multiple valence electrons, which reduces the repelling reaction. C. There are two main forms of electricity 1. The thermal conductivity and electrical resistivity of uranium are 27 W/m and 28.10-8 ohm.m respectively. When heat travels by conduction through a heat conductor, the heat is passed on from one … Aluminum is a very good conductor of electricity. Answer. Silver Conductivity “Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). An insulator does not allow electric current to pass through it. Electrical wires may be made of copper or aluminum metal, both of which conducts electricity, but copper is a much better conductor than aluminum and a safer option. Semi-conductors, however, can become more effective electrical conductors when heated or combined with other elements. Some of these minerals are useful for our health. If you see the structure of graphite, only three of the four carbon atoms are used for bonding. Material such as silver is the best conductor of electricity. It contains some salts and minerals dissolved in it. While metallic substances make good conductors of electricity, non-metallic substances usually do not. Most metals, such as copper, are good conductors, whereas most other non-metal materials are bad conductors, or insulators. The electrons then move freely throughout the electron sea. For instance, silver is the best conductor in the "conductors" list, offering easier passage for electrons than any other material cited. Chandramohan P.R. Copper is still the most popular material used for wires because it is a very good conductor of electrical current and it is fairly inexpensive when compared to gold and silver. Tungsten and Bismuth are metals which are poor conductors of electricity. Vinegar is a good conductor of electricity as it as an acid.But it is aweak conductor.Vinegar is acetic acid, which is a weak acid, so it is a weak conductor of electricity.A strong conductor of electricity can be Hydrochloric acid thumb_up Like (1) visibility Views (31.6K) edit Answer .
