Bad Conductor of Electricity
Materials with higher electric resistance and low conductivity are called bad conductors. They are called insulators in general. The resistivity of the insulators is higher than that of the conductors and semiconductors.
Important information about the bad conductor of electricity is provided below. It will be beneficial for understanding the basics of the conductivity of electricity.
- Insulators do not conduct electricity even at a high temperature. So they are bad conductors of electricity.
- Insulators provide high resistance to the flow of electricity and have heating effects.
- The forbidden energy gap between the conduction and valence shells is very high. So the flow of electrons is not possible.
- Examples of Insulators are plastic, glass, wood, dry cotton, and ceramic.
- It was used in electric transmission and heating purposes applications.
- Types of Insulators used in electric power transmission: Pin, Suspension, and Strain insulators.
