when the 'sea of electrons' within the material are free to move from one area of the conductor to another. This is caused by a charge being placed on either end of the conductor, which will attract the negative electrons to the positive charge, and repell them from the negative charge, hence creating a flow.

Inside solid electrical conductors electricity flows when?
Free electrons move toward positive charges
Why are ionic compound non conductors of electricity in solid and rare conductors of electricity in molten state?
The reason they are in solid and molten states is because of there electricity conducting capability's
Can copper conduct electricity in its solid form?
Yes. Metallic copper is one of the best of all conductors in solid form and therefore is commonly used for electrical wiring.
Is ionic solutions poor conductors of electricity?
(in short) No, whilst in their solid state ionic crystals are very poor conductors of electricity, however when molten or dissolved their ions are able to carry charge, therefore they are very good conductors of electricity when molten or dissolved in e.g. water. Pure water is a very poor electrical conductor too, it's the dissolved ions that carry the charge.
Will an ionic compound conduct electricity as a solid?
Ionic compounds are conductors in solution or melted.
When are salts excellent condutors of electricity?
False. A salt solution is full of positive and negative ions making it a good conductor of electricity.
What are the differences between a metal substance and a non-metal one?
Metals are good electrical and heat conductors. They are malleable, ductile, and generally solid at room temperature. Nonmetals are poor conductors of heat and electricity. They form brittle solids and are nonductile. They are generally liquids or gases at room temperature.
How do solid nonmetals differ from solid metals?
Metals are good conductors of electricity and heat. Also, they have a "metallic lustre", i.e., their surface shines.
Why does an apple produce electricity?
Electrochemical reaction occurs when electrolytes comes into contact with electrodes (solid conductors).
What solid that is a good conductor can be made into ornaments?
Metals are good conductors of electricity and are sometimes made into ornaments.
The electrical current in solid metallic conductors is the effect of what?
It is the flow of negatively charged particles, i.e. electrons.
Why is table salt a poor conducter of electricity?
Usually, solid ionic compounds are weak conductors of electricity. Aqueous solutions of ionic compounds are good conductors though as they have free ions for conductivity. When table salt is dissolved, the solution conducts electricity well.
