Brief explanation on dielectric?
86397
A dielectric, or electrical insulator, is a substance that is highly resistant to flow of electric current. and has a relative permittivity greater than unity.

Ok, i am an electronics teacher, but it will be very lengthy and cumbersome to explain, because you have to go as deep as electrons and positive and negative charges, so i can advise you to go to www.wikipedia.com and you will find a satisfactory answer.

capacitor is a energy storing device( in electric field)\nand the stored energy will be there for a long time as a field between the plates of the capacitor unless there is a closed circuit involving the legs of the capacitor.\n\neven in a small capacitor, a lot of energy can be stored which when discharges through a hima being may prove to be fatal. even in low resistance or impedance circuits, this discharge may result in unwanted behaviours in the circuits. every time when a capacitor is connected into a circuit, care is taken so as to discharge the energy in it so as to make it function as a new one without any stored energy. and the discharging is done by shorting, that is connecting the legs of the capacitor.

Proper Voltage of Tolerance that a body can take is not harmful, but more than the tolerable can get body organs cooked.  \nElectricity never reamsin in the human body it just pass through.. for a brief millisecond...\n\n-- Hope this helps.. Goodluck =)

The following refers to Coulomb force between two charges in a single uniform medium, not the two-medium situation described in  the question.\nAnswer 1 is helpful but the lack of exponent signs makes it misleading. The force is inversely proportional to the square of the distance, so the simplified formula is \nF = k * q1 * q2 / r^2 \nk is a constant = 8.99*10^9 N m^2 / C^2 (C is charge in Coulombs). Thus if q1 = q2 = 1 Coulomb, and q1 is separated from q2 by r = 1 meter, the force is 8.99*10^9 N or 2.01 billion pounds! \nThe above simplified formula is a contraction of the full formula (see ref.),\nF = q1 * q2 / (4 * pi * epsilon * r^2)\nin which k is replaced by 1/(4 * pi * epsilon), where epsilon is the product of epsilon0, the electrical permittivity of the vacuum (= 8.85 * 10^-12 c^2/(N m^2)), and kappa, the dielectric constant which = 1 for vacuum and is assumed in the simplified formula.\nFor two segments of distance as you specify, first solve for F1 and F2, each as a function of a particular distance (r or d - r) and dielectric constant. Then my inclination would be to try the sum-of-inverse square root solution which works for a similar situation, gravitational force F at distance R, computed from F1 and F2 at partial distances R1 and R2, where R = R1 + R2, \n1/SQRT(F) = 1/SQRT(F1) + 1/SQRT(F2)\nSorry I can't be more definite than that.

The best answer you can get is by going to howstuffworks.com. They have a very detailed description.\n\nBut basically, capacitors store electric energy and release it when it is needed most. A capacitor has two metal plates inside it, to hold the charge, and a material called a dielectric, which could be just about anything that is non-conductive, to keep the plates from touching each other. (I think that's what you were asking about the material between the capacitor.)\nThe one plate connected to the positive power loses electrons to the power source, and the other is connected to the negative, and gains electrons, thereby becoming electrically charged.\nA capacitor can be used to smooth out a DC voltage, supply extra power to a motor on start-up, or a large number of other things.\nBy the way, capacitance is measured in Farads, or, more commonly, micro-farads, nano-farads and pico-farads, which are very small parts of a farad. 10 to the power of -6, -9, and -12, respectively.

A dielectric material is one that doesn't conduct electricity and can also be referred to as a conductor. This means they don't have many "free" electrons zooming throughout the material, ie not very many electrons that are tied to one specific atom in your solid. Asbestos and diamond are both examples of conductors.

michael b,\n\nthis is a heat transfer question in\napplied maths,physics or engineering\nthere are a lot of equations and \ntheorems in it and it is quite a big \nsubject\n\ngo to your nearest central library,\nask to see open university course\nMST207,unit10-it's the best i've seen\ncovering this subject-you're right,it\nhas a lot to do with home insulation- \ngood stuff-an example of maths being\napplied to the real world\n\ni hope that this helps

A quote from the first source, "This phenomenon, which is called dielectric breakdown, occurs in air at an electric field strength of about Emax = 3 x 10^6 V/m."\n\nPaschen's law describes dielectric breakdown of a gas.  Given this and your problem, >0.6m separation will theoretically prevent arcing.\n\nOther sources note that arcing will occur over longer distances with dust, moisture, contaminants, etc. being present in the air.\n\nCheck out the sources and/or google "paschen's law air breakdown"

if u recollect the equation,\n             resistance (r)= pl/A;\n        where p=specific resistivity\n                   l= length\n                   A= cross sectional area \n               Area = pie(3.414) * r2\n                  \n              but diameter is twic the radius.\nhence insulation thickness is dependent on pipe diameter.

There are only two types of electric charges that can conduct electricity:  electrons and ions.\n\nVegetable oil has no free electrons.\n\nVegetable oil with some dissolved atmospheric moisture might be slightly conductive because the water can be ionized, but dry vegetable oil has no ions.\n\nTherefore, it is safe to say pure vegetable oil is an insulator and not a conductor (at low voltages, say, below 600 Volts).

An insulator is a material containing no electrical charges. When a voltage is sent across an insulator, no charges flow, so there is no electrical voltage\n\nGenerally,all non metals materials are good insulators.Such as plastic,glass,rubber(frying pot handle)
