Insulators are materials which do not conduct electric current, and thereby, offer high resistance to the flow of charges. Insulators like bakelite and hard rubber have very high resistivities in the range of 1014 to 1016 Ωm.

Material with Resistivity more than 10^14 Ωm

Bakelite
- Bakelite is a type of plastic that has a resistivity higher than 10^14 Ωm.
- It is an insulating material, meaning it does not conduct electricity easily.
- Bakelite is commonly used in electrical insulators, such as switches and circuit boards.
Copper, aluminum, and silicon are all conductive materials with much lower resistivity compared to Bakelite. Copper, for example, has a resistivity of around 1.7 x 10^-8 Ωm, making it an excellent conductor of electricity. Aluminum and silicon also have lower resistivities compared to Bakelite, making them unsuitable for applications where high resistance is required.
