In a torch, the metal components such as the wires and contacts are conductors of electricity, while the plastic casing and rubber buttons are insulators that prevent electrical current from flowing where it shouldn't.
No, a substance cannot be both a conductor and an insulator simultaneously. Conductors allow the flow of electricity, whereas insulators do not. Materials are classified as conductors or insulators based on their ability to conduct electricity.
No, sodium is a metal and is not a semiconductor. Semiconductors are materials that have conductivity between that of a conductor and an insulator. Sodium is a good conductor of electricity due to its metallic properties.
No, candle wax is not a conductor of electricity. It is an insulator.
Paper is generally not a good conductor of electricity due to its high resistance. However, paper can become conductive when it is coated with conductive materials like graphite or silver ink. Overall, paper is considered to be an insulator rather than a conductor.
Ceramic is not a good conductor of electricity. It is considered an insulator, meaning it does not allow electricity to flow through it easily. However, some ceramics, like piezoelectric materials, can conduct electricity under certain conditions.
The handle of the torch is typically the insulator, as it is made of non-conductive materials like plastic or rubber to prevent electric shocks. The filament or bulb inside the torch serves as the conductor, allowing electricity to pass through and produce light.
Conductor
Since elastic is rubber and rubber is an insulator, then yes, elastic is an insulator.
insulator, conductor and semiconductor

It is an insulator
Insulator
insulator
It will depend on the specific book and what materials have been used to create it. In most cases, a standard bound book of paper and standard cover will be an Insulator. With specific inks or metallic materials it could be a conductor.
is a pen a insulator of conductor
Wind is neither a conductor nor an insulator. It is simply moving air. Wind does not have the ability to conduct or insulate electricity like materials such as metals or rubber.
A radio can be considered an insulator because it is made of materials that do not easily conduct electricity. The outer casing of the radio is typically made of plastic or non-metallic materials that do not allow electricity to flow easily.
