Electronic conductors and insulators Flashcards
(10 cards)
What is a conductor?
A material that allows electric current to flow easily through it.
Give three examples of conductors.
Copper, aluminium, and silver.
What is an insulator?
A material that resists the flow of electric current.
Give three examples of insulators.
Rubber, plastic, and glass.
What is a semiconductor?
A material with electrical conductivity between that of a conductor and an insulator.
Give two examples of semiconductors.
Silicon and germanium.
Why are conductors important in electronics?
They are used to connect components and allow current to flow through circuits.
What are common applications of insulators?
Coating wires, preventing electric shocks, and protecting circuits.
How are semiconductors used in electronic devices?
As the basis for components like diodes, transistors, and integrated circuits.
What property makes semiconductors unique?
Their conductivity can be altered by adding impurities (doping) or by external factors like light or heat.
