Conductors and Insulators

1. Four conductors used mostly in the electrical industry is Copper, Silver, Aluminium and Steel.

2. Four Insulator materials used mostly in the electrical industry is Air, Rubber, Glass, and Plastic.

  3. There is many different conductors and insulators available in the electrical industry this is because due to the environmental factors in electrical work you have to use certain types of insulators and conductors to suit the condition of work being done, and to keep yourself safe.

  4. Environment factors do affect conductors and insulators through aspects such as temperature. Conductors have a positive temperature so a increase in temperature increases their resistivity and resistance. Whereas Insulators have a negative temperature so they are liable to decrease their resistivity and resistance with an increase in temperature.  A simple way to calculate the resistance of a conductor is to use the formula R=p*L/A=ohms.

  5. In electronic manufacturing the conductors used are cooper and aluminium and semi conductors such as silicon and germanium which is used in transistors and diode.
