A torch (flashlight) is a convenient lighting device, where the energy source and the illumination are provided in a utilitarian form. (Headlamp, handheld, etc.)
A complete electrical circuit is needed to operate the device, and an integral switch completes the circuit.
The batteries naturally have their own built-in insulation to prevent premature discharge, and otherwise the circuit, as with all other electrical circuits, needs insulating from accidental discharge.

Materials that are not good conductors or and not good insulators are called?
Semiconductor
What does an electrical insulator have?
Electrical insulators are made from materials that are poor conductors of electricity. Metallic elements are good conductors, non metallic elements are poor conductors. Some materials used as insulators are, paper, glass, ceramics, rubber and plastics.
Are insulators dull brittle and poor conductors?
Insulators are conductors
What materials make the best conductors and insulators?
Conductors- Most types of metal. Copper and Aluminium are used these days. Silver is a very good conductor but it is expensive. Insulators- rubber, plastic and wood are good insulators in the solid state.
Are materials that can be statically charged conductors or insulators?
Either one can acquire a static charge.
What parts of a torch are insulators?
The Insulators in a torch is the rubber. I think.
What are materials that are poor conductors of electricity called?

Materials that are poor conductors are what?
normally called insulators
What Types of building materials are conductors and insulators?
electrical

Why some of the materials are insulators?
They are bad conductors ,they do not allow heat transfer.
Materials that are sometimes classified as insulators and sometimes as conductors are called?
semiconductors
How are materials divided into conductors insulators and semi conductors according to the atomic theory?
by their ability to accept electrons
