NOTE

CONDUCTORS AND INSULATORS

Conductors are materials that allow the flow of electric current. The types of conductors include metals like copper, aluminum, and silver, as well as electrolytes like saltwater.

Insulators are materials that do not allow the flow of electric current. The types of insulators include rubber, plastic, glass, ceramic, and wood.

Differences between conductors and insulators

Property

Insulators

Electrical

Allow the flow of electric current   

Do not allow the flow of electric current    

Examples

Copper, aluminum, silver, electrolytes (saltwater)     

Rubber, plastic, glass, ceramic, wood       

Uses

Used in electrical wiring, power transmission lines, electronic circuits, and conductive coatings    

Used to insulate wires, cables, electrical components, and electronic devices to prevent the flow of electricity

 

Uses of Conductors

  1. Conductors like copper and aluminum are used in electrical wiring to carry electric current safely and efficiently within buildings and infrastructure.
  2. Conductors such as aluminum and steel are used in overhead power transmission lines to transport electricity over long distances from power plants to consumers.
  3. Conductive materials like copper are used in printed circuit boards (PCBs) and integrated circuits to establish electrical connections between components.
  4. Some conductive materials are used as coatings to prevent static buildup or to shield electronic devices from electromagnetic interference (EMI).

Uses of Insulators

  1. Insulators like rubber, plastic, and ceramic are used to cover electrical wires and cables, preventing electric current from leaking out and protecting against electrical shocks.
  2. Insulators are used to separate and protect electrical components within devices and equipment, preventing short circuits and ensuring proper functioning.
  3. Insulating materials are used in the construction of electronic devices to prevent unwanted electrical connections, isolate components, and protect against environmental factors like moisture and dust.
  4. Insulators are used in high voltage equipment such as transformers, capacitors, and insulator strings on power lines to prevent electric arcing and maintain electrical isolation.
