rubber
It is when an object is transferring energy through the object easiily
air can become a good conductor when it is heated to very high temperatures
It's not the object that matters, but what it's made of . A metal cup will be a very good conductor, and an expanded polystyrene one a very poor conductor.
Plastic is an insulator where as metal is a good conductor

An object is a good conductor when electricity, heat or another form of energy can travel through it easily.

a good conducter of electricity needs what object to work

Magnesium chloride is a good conductor if melted or dissolved in an ionization promoting solvent; as a solid it is not a good conductor.
Well, if you have a functioning (=closed) circuit, and introduce an unknown object, then if the circuit is still functioning (=closed) then the object is a conductor. If it stops working, then it's either an insulator or an very poor conductor.
A good insulator means a bad conductor. It is the opposite of good conductor.
