A metal can transmit the electron and the force so it is not a dielectric to electrons.
Dielectrics must be electrical insulators. Metals are good conductors. As a result, metal can never be used as a dielectric in a capacitor.
The conductors of the transmission line act as a parallel plate of the capacitor and the air is just like the dielectric medium between them.A capacitor is a device used to store electrical charge and electrical energy.
They are used to store charges, like a capacitor.
A capacitor is rated to operate in a certain temperature range. It is not designed to operate as a variable temperature device. The temperature of a capacitor depends primarily on the ambient operating temperature around it plus the frequency of operation (no of charge / discharge per second). Normal electrolytic capacitors used in consumer electronics are rated from 85 degrees Celsius to 105 degrees Celsius.
no, the type of metal used is platinum which is unfavorable to metal or magnet.
Via is used for connecting successive metal layers like metal 1 to metal 3 etc, whereas contact is used to connect the poly-silicon to the metal 1 for external pin connections
Any dielectric material can be used to separate the two metal plates inside a capacitor. This includes polymer, paper, glass or even air (although air is seldom used now).
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.
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.
Capacitors are named after the type of dielectric used to separate the plates. So a mylar capacitor uses a mylar dielectric. Mylar is the trade name for a form of plastic film manufactured by Dupont.

Capacitors are, in principal, two parallel plates separated by something (the dielectric). This dielectric can be many things, in fact most non-conductive things, air is just one. Warning, heavy science (way way above my level) http://en.wikipedia.org/wiki/Dielectric#Some_practical_dielectrics Photo of variable air dielectric capacitor, used to be used to tune radios for example. You can see the plates and air gap. http://en.wikipedia.org/wiki/File:Variable_Capacitor.jpg G
A cylindrical capacitor is a type capacitor in which two conducting cylinders are used and the dielectric medium is placed in between them .The outer most cylinder is earthed .The capacitance of these capacitors are higher than other
Between the two plates of a capacitor lies a medium with a specific dielectric constant. Placing a fish between these plates changes to dielectric constant. If the fish is fresh it will be strong and tight, thus possessing a higher dielectric constant. If the fish is older, it's dielectric constant, or body, will be weaker due to decay.
A capacitor is a circuit component that stores energy in the electric field set up between its plates.Capacitors are named after the dielectric used to separate their plates (e.g. 'mica' capacitor), and there are lots of different types of dielectric used (too many to list), so there are a corresponding number of types of capacitor.But you can also categorise a capacitor as being 'polarised' or 'non-polarised'; electrolytic capacitors are 'polarised', which means that they must be connected into a circuit while taking into account the polarity of their terminals.Finally, you can categorise them as being 'fixed value' or 'variable'.
Yes you can. But the variable one is used so that you can very the frequency and it cant be varied anymore if you use a fixed capacitor.
A metal film capacitor is an electrical part that holds energy electrostatically inside of an electric field. The capacitor has a dielectric which separates two electrical parts which are made out of thin film.
In radios that aren't solid state, and use variable capacitors for tuning, the air-dielectric variable capacitor is the almost universal choice for radio frequency applications. More information on air variable capacitors is available at www.orenelliottproducts.com.
