[SOLVED] Can Hydrogen have a DC Circuit? I'm thinking of the hydrogen atom like it might be a DC type of electrical circuit, just for fun, but I am not sure what values to use for a couple of simple equations. Can somebody help me out? The equation is V=I*R I found an impedance value, Z, in NIST's list of constants and stuff, a factor they call "Characteristic Impedance of the Vacuum". That Z value = 376.73 ohms. Can I use that as R? I know the BE for the H 1s electron is 13.06 eV, and it looks like I can use it for V, but I'm not sure since it has units of "eV". Can I use it for "V" as it is or do I have to change it or do something else? Maybe I can use the charge, Q, of the electron and calculate "V" from capcitance "C" using C = Q/V, but I have the same units problem. Thanks for any help! Hey, maybe I can use this for a science project!
