Dielectric
- A capacitor is an electrical component designed to store electric charge.
- A dielectric material separates the conducting plates of a capacitor.
- The capacitance of the space between the plates will increase by a factor of the dielectric constant if the space is completely filled with a dielectric material.
- The dielectric constant of the material affects how much energy a capacitor can hold when a voltage is applied.
Ebonite
- Natural rubber is vulcanized over a long period of time to produce a hard rubber called ebonite.
- The linseed oil and sulfur concentration in ebonite can range from to .
- Its name refers to the fact that it is intended to be used as a substitute for artificial ebony wood.
Hence, ebonite is a dielectric material. This is due to the poor electrical conductivity of ebonite; It is an insulator. It lacks the free electrons needed for conductivity and is difficult for electrons to move around.
