plz do it in full explanation .
Answers
Answer:
good conductor -> iron nail
bad Conductor -> Coal Piece
Explanation:
Iron Nail is a good conductor of Electricity because it is made up of Iron i.e Fe. It has free flowing electrons which move across when electricity flows through it.
Coal Riece is bad conductor of Electricity because it is made up of carbon C which contains 4 electrons outsides which are bounded by making 4 covalent Bonds with other carbon atom, so it does not contains the free electrons for the electrons to flow. So it is a bad conductor of Electricity.
Answer:
Iron nail-Good conductor
coal piece-Good conductor
Iron nail conducts electricity because they are metals.Metals conduct electricity because they have free electrons.
*Coal is one of the fossil fuels which highly conducts electricity.Coal is used for producing electricity in India.But India is not self sufficient in coal.They import coal from other countries.
That is why the need for using sun light (solar energy) as the source of energy is advisable
