Question

What are Conductors? How are they useful in an electric circuit?

Answer 1

Answer:

A conductor is one which allow flow of current through it. ... In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.

Answer 2

• With the application of voltage, electrical charge carriers, typically electrons, move easily from atom to atom.
• The ability to transfer anything, such as electricity or heat, is defined as conductivity in general.

• The best electrical conductor that can be found in everyday life is pure elemental silver.
• Conductors include copper, steel, gold, aluminium, and brass.
• Solid metals moulded into wires or engraved onto circuit boards are used as conductors in all electrical and electronic systems.

• Electrical conductivity is good in some liquids. Mercury is a great case in point. A fairly conductor is a saturated salt-water solution.
• Because the atoms are too far apart for a free interchange of electrons, gases are often poor conductors.
• A sample of gas, on the other hand, can behave as a fair conductor if it includes a large number of ions.
