What is a good electrical conductor when melted and is a good insulator in its solid state?
Greef
Glass is a good conductor when melted. Most precision glass melters use gas burners to get the glass to a molten state, then they use electrodes immersed in the glass to electrically heat it to the required temperature.

How much solid wax makes one ounce of melted wax?
One ounce. No mass is lost in the phase change from solid to liquid wax.
What is a semiconductor?
Semi-conductor is a material in which the energy band gap between the conduction band and valance energy band is very less (around 1V) which is in between conductors and insulators So, with just a an excitation energy of around 1v changes the state of semi-conductor to wither conductor or insulator .
Can electricity pass through plastic?
For the flow of Electric Current, the material must contain free electrons. If there are no free electrons, then to conduct electricity the applied voltage must exceed breakdown voltage. Plastics under ordinary state does not have free electrons but if high voltage is applied then it can start conducting.
How do you calculate diameter of a copper wire conductor and how do we calculate resistance of a copper wire conductor of a particaular length?
You go to the NEC and look at the chart for developed length and the ambient temperature and the load factor and if it solid or stranded wire as stranded allows for more voltage
What is the difference between electronic and electrical?
Its all electrical, but referring to electronics would be solid state devices such as tiny resistors ,tranistors soldering work found on devices such as Computer chips and Vehicle ECU's
Is a solid a conductor or insulator?
It depends on what it's made of. A metal is a conductor and a nonmetal is an insulator.
Is NaCl an insulator or conductor?
Hi, Salt itself is an insulator of electricity. The conductivity of any solution depends on the movement of ions. Ions are the charged species of the atom. In salt the movement of these ions are not possible. Thus, it is a bad conductor. Hope this helps.
Is brass an insulator or conductor?
Brass will conduct both electricity and heat. So brass is a conductor, but not an insulator.
Which non metallic solid is not an electrical insulator?
graphite
Is glass a conductor or insulator of electricity?
Glass in a molten state is a conductor of electricity. When glass turns to a solid state it becomes an insulator.Basically, glass in a window or a test tube would be the solid state and so it is a insulator of electricity.
Is a glass dish a conductor of electricity?
Glass in its solid state is an insulator of electricity.
Is a magnet a insulator or conductor of electricity?
Assuming you mean electrical conductor / insulator, most bar magnets are made of solid metal, either iron, neodymium or an alloy of aluminium nickel and cobalt, so they conduct electricity. There is one type of magnet called a ferrite magnet which does not conduct electricity - they are the type often found in loudspeakers.
Is Magnesium Chloride a good conductor?
Magnesium chloride is a good conductor if melted or dissolved in an ionization promoting solvent; as a solid it is not a good conductor.
Solid NaCl her what is the electrecally conduter?
Solid sodium chloride is not an electrical conductor.
Is iodine an electrical conductor?
Iodine, either in its solid state or dissolved in alcohol, is not a conductor of electricity.
Is NaCl a good conductor?
Sodium chloride is an electrolyte only in water solutions or when is melted. Solid sodium chloride is not a conductor of electricity.
What is the condutivity in salt?
It is a ionic compound. Solid is not conducting.
