Which of the following are electrically insulating materials?

1. Lucite

2. Mica

3. Bakelite

Select the correct answer using the code given below.

Insulators:

• Those substances through which electric current cannot pass easily are called insulators.

• These materials provide electrical insulation between conductors hence are called insulants or insulators.

• These materials provide mechanical support to conductors and help in the transfer of heat.

• EX: Glass, Mica, Lucite, dry Air, Bakelite, vacuum, etc.

Note:

Lucite (polymethyl methacrylate):

• It is also called Plexiglas.

• It is a synthetic organic compound of high molecular weight.

• The material has high dimensional stability and good resistance to weathering and to shock.

• it is colorless and highly transparent.
