Okay, you discharge a capacitor, and weigh it...then,
You charge the capacitor, and weigh it.
Is the weight the same?
Each electron weights approx. 10 e -31 kg.Okay, you discharge a capacitor, and weigh it...then,

Dawad, read the 2nd reply. It indicates that it is a function of the materials used...Electrons shift the plate.
"No, it is the same weight. When a capacitor is uncharged, the number of electrons is equal on both sides of the capacitor. When a capacitor is charged, the electrons on the positive side of the capacitor leave and go to the negative side of the capacitor (while they aren't actually the exact same electrons, you can think of it like that). Therefore, the capacitor's weight stays the same."
Is a capacitor heavier when charged?
It would be different on an incredibly sensitive scale.
Eh, good question.Okay, you discharge a capacitor, and weigh it...then,

I am going to risk proving I'm a moron.According to convential current flow theory there would be no change in weight. As electrons piled onto the chaged plate (-), they would be drawn from the other plate in the capacitor (+), leaving 'holes'. At discharge, those electrons would flow back to their holes, creating a situation where there is no alteration in overall electron content between the two plates taken as a whole. As convential current flow theory is the basis of all solid state theory, it is plain to see that a charged capacitor will weigh the same at any state of charge. Anyone who disagrees with this obviously has no concept of electrical theory, says the guy who works as an electrical engineer and once built a functional lie detector as a school project. So nyah!
EDIT: Before you bother proving you're a moron by arguing with me, go read about the P-N junction.
Oh dangit you're right, Wirey, the net charge remains the same, the charge carriers would repel the same number the other side to form the holes.
I won't edit my previous posts so the world can recognise my moronity.
Althouuuugh, while the net charge remains the same, there is stored energy in a charged capacitor, and not in a discharged one... wouldn't that affect the mass in some clever Einsteiny way?
And oi oi, I thought P-N junctions were used for diodes and transistors (NPN PNP), wasn't aware the same principle worked with capacitors.
Well, i was reading this:Well guys, I am the moron that started this. I'll check the interweb for more info.
Well, i was reading this:
Does a charged capacitor weigh more than a discharged capacitor? : askscience
Not a bonedry yes or no, seems the bone is still in the body.
There is a little rule called conservation of Mass and another called m=E/c^2.Okay, you discharge a capacitor, and weigh it...then,
You charge the capacitor, and weigh it.
