Give an example of a bad conductor.

Hint: Insulators, also identified as bad conductors, are materials that block electrons from freely moving from one element’s particle to another. If we implement a charge to such an element at any location on the surface, the charge keeps in the same place and does not diffuse across the surface.

Complete step-by-step solution:
An electrical insulator is a matter in which electric current does not move freely. The atoms of the insulator have tightly constrained electrons that cannot readily move. Other materials, semiconductors, and conductors carry electric current more quickly. The property that defines an insulator is its resistivity; insulators have larger resistivity than semiconductors or conductors. The most general examples are non-metals.
All insulators are electrically conductive when enough voltage is applied that the electric field breaks electrons away from the atoms. This is identified as the breakdown voltage of an insulator. Some substances such as glass, paper, and Teflon, which have large resistivity, are excellent electrical insulators. Even though they may have tinier bulk resistivity, a much higher class of materials is still large enough to prevent meaningful current from flowing at regularly used voltages and thus are used as insulation for electrical wiring and cables. Examples involve rubber-like polymers and most maximum plastics, which can be thermoset or thermoplastic in nature.
The standard process of charging such elements includes charging by rubbing and charging by induction. Distilled water does not carry electricity because it does not contain any ionic compounds dissolved in it.
Insulators are utilized in electrical equipment to maintain and separate electrical conductors without passing a current through themselves. An insulating material utilized in bulk to protect electrical cables or other equipment is estimated insulation.
Examples of bad conductors: Plastic, Wood, Glass.

Note:The term insulator is also more specifically applied to insulating supports used to attach electric power distribution or transmission lines to poles and transmission towers. They maintain the weight of the suspended wires without passing the current to flow by the tower to the ground.
