Which of the following is NOT a conductor?

The correct answer is Hand rubber.

Key Points

• Conductor

  • ​A substance or material that permits the flow of electricity is known as an electrical conductor. When voltage is provided, electrical charge carriers, often electrons or ions, travel effortlessly from atom to atom in a conductor.

  • Several types of electrical conductors include - Human Body, Copper, Aluminium, Silver, Gold, Graphite, Platinum.

  • Electric charges can easily pass through an electrical conductor. Conductivity is the ability of conductors to "conduct" electricity. Such materials provide less barrier to the movement of charges. Because electrons can freely flow through conducting materials, charge transfer is simple. Such materials offer less opposition or “resistance” to the flow of charges. Conducting materials allows easy charge transfer because of the free movement of electrons through them.

• Electrical Conductor Properties

  • The flow of electrons and ions via a conductor is constant.

  • Since there is no electric field inside a conductor, electrons can move around freely.

  • Inside a conductor, the charge density is zero.

  • Free charges are only present on the conductor's surface.

  • A conductor's points are all at the same potential.

  • Many metals are effective electrical conductors. This is the rationale behind the use of metals in electrical appliance parts. Insulators are the plastic casings that shield electrical conductors. We won't experience an electric shock thanks to it.

Additional Information

• Solid Conductor
• Metallic Conductor: Silver, Copper, Aluminum, Gold, etc.
• Non-Metallic Conductor: Graphite
• Alloy Conductor: Brass, Bronze, etc.
• Liquid Conductor
• Metallic Conductor: Mercury
• Non Metallic Conductor: Saline Water, Acid Solution, etc.
• Copper Conductor is the most common material used for electrical wiring.
• Gold Conductor is used for high-quality surface-to-surface contacts.
• Silver is the best conductor on the Conductors list.
• Impure Water is listed in the Conductor List but it has less conductivity.
