Which of the following is not a dielectric?a) ebonite b)micac)waterd)oil
Answers
Answer:The dielectric is a material through which no electric current passes. Here the given materials-plastic, mica and porcelain are all the dielectric because current can not pass through them.
Answer:
Water is not a dielectric because anything that prevents the flow of charge is considered to be an electrical insulator. Either electrons or ionic chemical entities can carry a charge. Liquid water is not an electrical insulator, making it not dielectric.
Explanation:
A dielectric substance is an ebonite. Hard rubber, also known as ebonite, is a substance that is produced by vulcanizing natural rubber for an extended length of time. From 25% to 80% of ebonite's composition may be sulfur and linseed oil. Its name refers to the fact that it is meant to be used as an artificial ebony wood substitute.
Mica is the dielectric used in silver mica capacitors. Low resistive and inductive losses give them excellent high-frequency characteristics, and they are also quite stable over time.
Various degrees of dielectricity exist in all lubricating oils. The use of a dielectric is commonly demonstrated via a capacitor. The electrical charge that is stored in a capacitor can be released later. A similar effect may be achieved via lubricating lubricants.
