Does coal is a good conductor of electricity?
Coal is a bad conductor of electricity.
What is the poorest conductor of electricity?
Bismuth and tungsten are two metals which are poor conductors of electricity. Dear friend, Tungsten and Bismuth are metals which are poor conductors of electricity. Stainless Steel is a poor conductor because it has an alloy structure.
Why is it bad conductor of electricity?
Materials that are poor conductors of electricity are called insulators. … The reason that they do not conduct electricity is that charges cannot move through them the particles and their electrons are locked into a solid structure.
Can a diamond conduct electricity?
Diamond. Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. … It does not conduct electricity as there are no delocalised electrons in the structure.
Is coal a metal?
Coal is non-metal. It is an amorphous form of Carbon. Coal is a substance formed from decayed plants and animals. Therefore, coal is not considered a mineral.

Is titanium a good conductor of electricity?
Titanium is not as hard as some grades of heat-treated steel; it is non-magnetic and a poor conductor of heat and electricity.
Is lead a poor conductor of electricity?
Lead being a metal is a bad conductor of electricity and heat. This is because it readily reacts with the atmosphere to form lead oxide which does not allow electricity and heat to pass through it. Hence lead is a bad conductor.
What are some bad conductors?
