warped space Posted February 27, 2013 Share Posted February 27, 2013 How is electrical resistance effected by reletivity 1 Link to comment Share on other sites More sharing options...
elfmotat Posted February 27, 2013 Share Posted February 27, 2013 Interesting question. I don't think I've ever seen anything like this worked out before. I suppose there would be two ways to approach it: either by considering how voltage and current are effected, or considering how resistivity and volume are affected. The effect on resistivity seems like a complicated problem. Of course, resistance is related to resistivity by area and length, both of which could be affected by a Lorentz boost. For the other approach, you could consider the EMF induced by a changing magnetic field. A boost will change the value of the magnetic field, and thus the EMF. The current will also change with a boost. I might work out a specific scenario later. Link to comment Share on other sites More sharing options...
Enthalpy Posted February 27, 2013 Share Posted February 27, 2013 This would first need to measure an ohmic value at a moving component. Maybe through an electromagnetic field, but the related effects must be split among propagation and local changes. Could you choose clearer thread titles?

You'll also want to factor in that electric fields and magnetic fields are relativistic transforms of each other. Link to comment Share on other sites More sharing options...
warped space Posted February 28, 2013 Author Share Posted February 28, 2013 Im fairly un professional to this so would you basically take the ohms at one point along the line and then take it in another place along a environmentally isolated wire that is at two hights from earth because gravitationally that changesthe relative time Link to comment Share on other sites More sharing options...
