I assume you mean insulators, which are vital for all sorts of purposes for housing conduit, eliminating or minimizing shock hazards. These are also called Dielectrics. One common substance- Waxed Paper has the very high dielectric of 540,000 Volts per cubic centimeter. so it makes sense to eat lunch in the generator room- maybe this was discovered accidentally. it was known in l909 as an old technical magazine of mine states it as a fact.
What else can I help you with?
In the electric series which materials is the most negative?
Fluorine is the most negative material in the electric series.
Which automatic practicles have a negative electric charge?
its electrons
In which direction do electric field points from positive to negative?
The electric field points from positive to negative.
Is it possible for electric flux to have a negative value?
Yes, electric flux can have a negative value if the electric field and the area vector have opposite directions.
How does the electric field direction change from positive to negative in a given system?
In a given system, the electric field direction changes from positive to negative when the source of the electric field changes its charge from positive to negative.
In the electric series which materials is the most negative?
Fluorine is the most negative material in the electric series.
What is negative charges on one material called?
Negative charges on one material are commonly referred to as "static electricity." This occurs when there is an imbalance of electrons, leading to a buildup of negative charge in that material. When this charged material comes into contact with another object, it can create an electric discharge or attract opposite charges. This phenomenon is often observed in everyday situations, such as when rubbing a balloon on hair.
What are the dieletric filed?
A dielectric field refers to the electric field present in a dielectric material, which is an insulator that can be polarized by an electric field. When exposed to an electric field, the positive and negative charges within the dielectric material shift slightly, creating an induced electric field that opposes the applied field. This phenomenon reduces the overall electric field within the material and enhances its capacitance. Dielectric fields are crucial in applications like capacitors, where they influence energy storage and the behavior of electric circuits.
How a dielectric polarized?
A dielectric material becomes polarized when an external electric field is applied, causing the positive and negative charges within the material to shift in opposite directions. This displacement of charges results in the formation of electric dipoles, which align with the field. The degree of polarization depends on the strength of the electric field and the material's properties, such as its permittivity. Once the external field is removed, most dielectrics return to their original state, though some materials may retain a degree of polarization, known as ferroelectricity.
Which automatic practicles have a negative electric charge?
its electrons
What are bound charges?
Bound charges are electrical charges that are not free to move throughout a material but are instead associated with atoms or molecules within a dielectric or polarized material. They arise when an external electric field polarizes the material, causing a separation of positive and negative charges at the atomic level. This results in the formation of dipoles, which contribute to the material's overall electric polarization. Bound charges are significant in understanding the behavior of dielectrics in electric fields, as they influence the material's response to applied voltages.
In which direction do electric field points from positive to negative?
The electric field points from positive to negative.
What material allows electric current to pass through?
Electric current flows in conducting materials such as metals. The best conductor of electric current is silver, followed closely by copper and then aluminium.
Is it possible for electric flux to have a negative value?
Yes, electric flux can have a negative value if the electric field and the area vector have opposite directions.
In the electric series which one of the following materials is the most negatively charged?
In the electric series, materials are ranked based on their tendency to gain or lose electrons. The most negatively charged material is typically rubber or ebonite, which has a strong affinity for electrons. This means that when rubbed against other materials, it tends to acquire a negative charge more effectively than others.
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 the build up of a positive or negative electric charge on a materials surface?
A positive or negative electric charge can build up on a material's surface through the gain or loss of electrons. This can occur through processes such as friction, induction, or conduction, where electrons are transferred between materials, resulting in an accumulation of charge.
