“Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity....
Sanitary fittings are generally coated with a layer of which metal ? 02:12 Which of the following is a bad conductor of electricity ? 03:15 Which of the following is a good conductor of electricity ? 02:32 Chemical effect of electric current is primarily used for which of the... 02:10...
process for assembling a metal conductor of electricity with an element is a substance is obtained by this process and assembly of refractoryTITUS,LESLIE
Carbon is a non-metal and therefore has covalent bonds. However, in this experiment, it exhibited metallic properties. Carbon in the form of graphite is the only non-metallic element that conducts electricity. As we all know,graphiteis composed of sheets of hexagons of carbon atoms joined by...
Copper is a chemical element, a reddish, extremely ductile (able to be drawn out into a thin wire) metal. It is an excellent conductor of electricity and heat. Where does copper come from? Copper is found in the free metallic state in nature. First used in 8000 BCE, it was a substitu...
When an electric appliance such as a heater has a metal casing, the makes the operator vulnerable to electric shock since metal is a conductor of electricity. To avoid electrocution, there must be some design considerations for the heater....
While metal is a conductor of electricity, it does not attract lightning strikes more than other materials such as wood or asphalt. Additionally, metal roofs are typically grounded and can dissipate the electrical charge from a lightning strike, which can help prevent damage to the home and its...
The only way to know if a circuit is good or bad is to make lots of them. METAL DETECTOR WITH PRINTED COIL Here is a metal detector kit with a rectangular coil made by etching a continuous track on a printed circuit board. The track starts at the outside of the top of one side ...
Purified water is again a bad conductor of electricity and so are the amines and alcoholic derivatives of amines. Therefore, to pass electricity through the reaction medium, either any electrolytic salt can be used or the alcoholic derivatives of amines can be doped with some chemicals such as ...
