Question

what are insulator ot poor conductor.​

Answer 1

Answer:

Materials like glass and plastic are poor electrical conductors, and are called insulators. They are used to stop electricity from flowing where it is not needed or where it can be dangerous, such as through our bodies.

Answer 2

• The degree of freedom with which electrons of various kinds of atoms may travel about varies.
• The outermost electrons in some materials, such as metals, are so loosely linked that they migrate chaotically through the space between the atoms of that substance under the effect of room-temperature heat energy.
• These virtually unbound electrons are referred to as free electrons because they are free to leave their particular atoms and float around in the space between neighbouring atoms.
