A theoretical question about mater/antimatter and capacitors
rgawron:
Let's assume that the experiment is done in a vacuum and there's a circuit as in attachment. Values of voltage/resistance/capacitance are insignificant.
Assume that the right terminals of capacitors and the wire that connect them is made from antimatter, all else is made from regular matter.
My question is, would the voltage observed on resistor be the same as with above terminals/wires made from regular matter?
RoGeorge:
That's an interesting question, such a can of worms! :)
My guess is that it will make no difference if the right side of the plates + the wire between them is made of antimatter. The reasoning is that the laws of nature, here the Maxwell's equations, does not change. They remain valid even for no matter at all, in vacuum, so I guess it doesn't matter the charge of elementary antiparticles.
Domagoj T:
Wouldn't the electrons, as soon as they pass from left side to the right, slam into the positrons of the antimatter side of the capacitor, leading to annihilation?
magic:
I suppose that if you push electrons into C1 then they will attract positrons to the other side of C1 and suck them out of C2, which will repel electrons from C2 and send them back to your voltage source. So probably everything will behave normally and electric fields and voltages will be same as usual, because one elementary charge is one elementary charge, regardless of what charge carrier brought it in.
Provided that you can prevent the electrons and positrons from jumping the gap and annihilating :P
If not, then you will perhaps get a rectifier or something like that :-DD

In a normal capacitor the electrons does not pass from one plate to another. They just attract or repel charges from the other plate, without jumping from one plate to another. Why would they jump between plates in a matter/antimatter capacitor?
