The conductors in capacitors are typically made from thin plates (or foil) of very ductile metallic materials to get the most capacitance. These materials must also be inexpensive and widely available. Aluminum is typically the workhorse material for most conductors in capacitors. Tantalum is used as well for the Cathode plate. Silver is also appears in silver-mica capacitors, and are used for high-accuracy audio applications. I believe that Manganese Dioxide MnO2 is sometimes used, as well, for the anode plate.
A capacitor is a passive electronic component consisting of a pair of conductors separated by a dielectric (insulator). When there is a potential difference (voltage) across the conductors, a static electric field develops in the dielectric that stores energy and produces a mechanical force between the conductors. An ideal capacitor is characterized by a single constant value, capacitance, measured in farads. This is the ratio of the electric charge on each conductor to the potential difference between them.

For higher frequency response which type of capacitor is used?
Probably vacuum ac capacitors.
Whether film capacitors can be replaced with ceramic or mica capacitor?
Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. However, mica capacitors can be replaced with ceramic capacitors in general.
Why Two 33pF capacitors are used with crystal oscillator?
c1 and c2 capacitors with crystal eliminates the Harmonics(Unwanted frequencies) .
What is the use of capacitors in fire alarm circuit?
Fire alarm system may be having some electronic devices and cards, in which some capacitors are used. Capacitors are part of any electronic cards.
Why do you use a dc capacitor in table fans while an ac capacitor in a ceiling fan?
there is no separate capacitors for AC and DC. All capacitors are same. Electrolytic capacitors are manufactured by creating a die-electric by chemical etching or electroplating on one plate. Such capacitors when connected in AC circuit dislodges the die-electric material and thus results in short circuit between the two parallel plates of the capacitor. For AC circuits only non-electrolytic capacitors should be used. The common type is oil impregnated paper capacitor.
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.
What type of elements are used as conductors?
Metals and alloys are used as conductors: copper, aluminium, silver.
Why don't we construct electronic device with conductor?
But we do, we do. Copper, Aluminum and other metals are used in many components because they ARE conductors. For example Copper is used in inductors & transformers; Aluminum is used as the plates of most capacitors.
How can you differentiate type of capacitors on the basis of dielectric material?
type of capacitors on the basis of dieelectri material
For higher frequency response which type of capacitor is used?
Probably vacuum ac capacitors.
What is an Annie Meter used for. It was manufactured in USA by Gould?
Type your answer here... to check motor capacitors.
What is a padder capacitor?
Padders are a type of Capacitors which are used at low frequency end of the radio dial.
What type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
Does table fans have capacitors?
The capacitors used in table fans is to start its induction motor.
Whether film capacitors can be replaced with ceramic or mica capacitor?
Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. However, mica capacitors can be replaced with ceramic capacitors in general.
What capacitors are used in ceiling fan?
A capacitor add torque to an electric motor that is designed to use them, they are called PSC or permanent split capacitor type motors. the capacitors terminals go to the Run and Start windings.
Which type of a capacitor is used for power factor correction?
A.C capacitorAnswerGenerally speaking power-factor capacitors are oil-impregnated paper capacitors -i.e. capacitors whose dielectric is manufactured from oil-impregnated paper. Power-factor capacitors are rated in reactive volt amperes, rather than in farads.There is no such thing as an 'AC capacitor', as all capacitors (other than polarised capacitor) can operate on either AC or DC.
