An electrical insulator is a material whose internal electric charges do not flow freely, and therefore make it nearly impossible to conduct an electric current under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily.
Electric discharge in gases occurs when electric current flows through a gaseous medium due to ionisation of the gas. Depending on several factors, the discharge may radiate visible light.

What is the difference in the electric field inside and outside a charged insulator?
The electric field inside a charged insulator is zero, while the electric field outside a charged insulator is non-zero.
How does an electric discharge occur?
An electric discharge occurs when a high voltage potential difference causes electrons to rapidly move through a medium, creating a flow of electric current. This flow of electrons can create visible light, heat, and sound, often seen in phenomena such as lightning or electrical sparks.
Is a rubber tube a conductor or a insulator?
A rubber tube is an insulator because it does not conduct electricity. Rubber is an electrical insulator due to its high resistance to the flow of electric current.
Is Rubber insulator or conductor?
Rubber, unless soaking wet, is an insulator (will not conduct electricity).
Is polythene an insulator or a conductor?
Polythene is considered an insulator. It has low electrical conductivity, meaning it does not allow electric current to flow easily through it. This property makes it useful for electrical insulation purposes.
What is the difference in the electric field inside and outside a charged insulator?
The electric field inside a charged insulator is zero, while the electric field outside a charged insulator is non-zero.
Why is electrical wir coated with plastic?
The electric wire is coated with plastic to serve as an electric insulator.
What is type of electric insulator?
Electric insulators can be made from various materials such as glass, porcelain, rubber, and plastic. These materials are chosen for their ability to resist the flow of electric current and prevent electrical conductivity. Insulators are used to support and protect electrical conductors to maintain safe operation of electrical systems.
What makes a good electrical insulator?
An electrical insulator is a material whose internal electric charges do not flow freely. Rubber, glass, paper, and Teflon, which have high resistivity, are very good electrical insulators.
What term is used to refer to the process of electrical discharge and the flow of electrical activity?
The term used to refer to the process of electrical discharge and the flow of electrical activity is "electric current." It is the flow of electric charge through a conductor, such as a wire, and is measured in amperes (A).

What is an electric conductor and insulator?
An electrical insulator is a material that resists electric current, and will not allow it to flow easily. Examples include glass and most ceramics. An electrical conductor is a material that offers very little resistance to electric current, allowing it to flow freely and easily. Most metals make excellent electrical conductors.
What is a arc?
discharge: electrical conduction through a gas in an applied electric field
What is the difference between electric and electrical?
Pronunciation. An electrical circuit is the exact same as the electric system.
