Talk about argumentative - it's not about an opinion - it's about facts: The facts are that: - Some hackers deliberately break the law - although a small minority of them - The term "hacker" means the

Vacuum has an inherent dielectric constant, known as the permittivity of a vacuum (or of 'free space'.) It also has an inherent inductance, known as the permeability of vacuum. These are values you

What if the material is different but the spacing and surface area are the same? Is the capacitance value always the same? No, because the dielectric constant of the two materials may be different and

Grow up

Whatever - I am not the one who went into a long diatrabe of OPINON of what a hacker is. And to then state that I don't comprehend words and ideas properly because I am an American! What childishness.

Lise, Jim

True. And also of the dielectric constant of the dielectric between the plates.

the of not potential current stores a charge. My idea would be that the charge is stored in the electric field. This is enabled equall

A good dielectric allows you to bring the plates closer together without arcing. Capacitance is a function of plate area and plate gap. Larger plates or smaller gaps give you a greater capacitance.

No, no, not ganging up, I just wanted to see if anyone really knew. I kind of know but it's been a while since I've had that class. Guess what, I didn't even have to dust off the old physics book

It has to do with the nature of the material. Plastics are good dielectrics because current can't flow through them easily. Metals make poor dielectrics because currents do flow through them. Of

Lise, Just for argument sake, by calling all hackers evil I feel you are throwing out the baby with the bath water. (or something like that :-) It is people who abuse hacking who are doing wrong. The

manifold, I haven't the foggiest. Hey you guys, you're ganging up on me/us. I can't say for certain about either view now. I only can say that the pro plates view seems to be backed by more

Jim, The purpose of the dielectric is to modify the field between the oppositely charged plates. The differences in the field leads to different capacitances. Rama

I have a right to disagree with you and I do, and I do so without calling you stupid. Boy that's some nationalistic comment, "because Americans haven't a clue about the meanings of words and even less

Doug, Nope, but I always thought that the charge was stored on the plates too, then my office mate where I was teaching electronics told me that it was stored on the dielectric. I guess I assumed he

Lise,

What about the chemical difference causes the difference in the dielectric constant? tubular, dielectric or

If a capacitor can be made of two plates in a vacuum and the charge is stored in the dielectric, can you explain to me how a charge is stored in a vacuum? Doug Hale
