What else can I help you with?
Modern capacitors which have high capacitance in small size use a dielectric?
Ceramic
What is the material use in the capacitor?
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.
Define mica capacitor?
A mica capacitor is simply one that uses the mineral mica as the dielectric or insulator between plates.
Which dielectric in this world has highest dielectric constant?
Strontium Titanate has a dielectric constant of 233. TDK in Japan makes Ultra-high Voltage Ceramic Capacitors using this as the dielectric material. Compared to distilled water at 76.7 - 78.2 (lowers as temperature rises). Types of glass can vary between 4 and 10.
Do capacitors have internal resistance?
1. The capacitor has Lead resistance in series with the capacitor2. Since most capacitor use Dielectric and they have a leakage resistance and it is parallel to the Ideal Capacitor.
What type of capacitor uses aluminum as its dielectric?
Electrolytic capacitors use aluminium as a dielectric.
Which type of dielectric is used most often in variable capacitors?
The type of dielectric most often used in variable capacitors is air. Also, trimmer capacitors often use mica.
How do capacitors classified?
capacitors are classified on the basis of dielectric material used inside it. For example the electrolytic capacitor consist electrolyte as dielectric mica capacitor consist mica as dielectric between plates and ceramic capacitor consist ceramic as dielectric.
Modern capacitors which have high capacitance in small size use a dielectric?

How can you differentiate type of capacitors on the basis of dielectric material?
type of capacitors on the basis of dieelectri material
What is the part of capacitor?
Capacitors consist of a insulating material, called a 'dielectric', sandwiched between two conductors, called 'plates'. Capacitors are devices that store energy(not charge!); this energy is stored in the electric field set up within the dielectric between the two plates when they are connected to an external potential difference.
What is the material use in the capacitor?
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on.

A mica capacitor is simply one that uses the mineral mica as the dielectric or insulator between plates.
What is the effect of inserting a dielectric other than air or vacuum between the plates of a capacitors?
Inserting a dielectric material between the plates of a capacitor increases the capacitance of the capacitor. The dielectric reduces the electric field between the plates and allows for more charge to be stored. This results in an increase in the amount of electric potential energy that can be stored in the capacitor.
Which dielectric in this world has highest dielectric constant?
Strontium Titanate has a dielectric constant of 233. TDK in Japan makes Ultra-high Voltage Ceramic Capacitors using this as the dielectric material. Compared to distilled water at 76.7 - 78.2 (lowers as temperature rises). Types of glass can vary between 4 and 10.
How are capacitors made?
A capacitor, in its simplest form, is two conductive plates separated by a dielectric.
