10 Points easy...?

Question

Please answer my questions.

-What to capacitors do?

-What are capacitors made from?

-How do they work?

-Where do you use them?

-How do you identify them and what are they mesured in?

Thank you so much!

Answer 1

-What to capacitors do?

Store energy in an electric field.

-What are capacitors made from?

Often from two plates of metal that are separated by an insulator.  There are many ways to make them.

-How do they work?

Opposite charges collect on the two plates.  This produces the electric field.

-Where do you use them?

In power supplies, in just about all electronics, in motor starters.  

-How do you identify them and what are they measured in?

They come in many shapes and sizes - too many for me to describe them all.  They are messed in Farads, but most are in micro Farads or smaller.

that is what search engines are for cos off the top of my head, sounds like a loada waffle! ;0)

Answer 5

By your actiond  you answered your question now give me my 10 pts LOLL

Answer 6

the only capacitor I am familiar with is the FLUX capacitor. It enables you to go back to the future.

mwa ha hah

Answer 7

a capacitor stores energy in an electric feild between two plates that are made from dielectric materials, for small charges there is a vacuum between the plates.

They work by allowing charge to build up on one plate, because of the gap between the plates, the charge cannot flow.  However, when a device, such as a batter, is connected to the two terminals, charge is then allowed to flow.  When the connection is removed, the charge is again in stasis.

They are often used in audio applications to remove white noise.  They can act (with other components) as a filter to remove unwanted frequencies.

They are identified on a circuit diagram as two parallel lines, perpendicular to the wire they are connected to, in real life they usually look like small cylinders.

The units for a capacitor is a farad, however they store charge in volts

Answer 8

capacitors :D physics! :D



1)A capacitor is an electrical/electronic device that can store energy in the electric field between a pair of conductors (called "plates"). The process of storing energy in the capacitor is known as "charging", and involves electric charges of equal magnitude, but opposite polarity, building up on each plate.

2)A capacitor consists of two conductive electrodes, or plates, separated by a dielectric, which prevents charge from moving directly between the plates. Charge may however be moved indirectly by external influences, such as a battery connecting the terminals. After removing the external influences, the charge on the plates persists. The separated charges attract each other, and an electric field is present between the plates. The simplest practical capacitor consists of two wide, flat, parallel plates separated by a thin dielectric layer.Assuming that the area of the plates A is much greater than their separation d, the instantaneous electric field between the plates E(t) is identical at any location away from the edges. If the instantaneous charge on a plate − q(t) is spread evenly,

not gona paste all here, it will look over crowded.

Answer 9

Capacitors capacite

They are made of capacite type material

They work very hard after all they are paid very well

You can use them anywhere accept in the shower

You can ID them by their name tag and we measure them in UFs.

Answer 10
