Component values in relativity theory

Oct 24, 2005 5 Replies

Has anyone encountered an analysis of the values of electronic components such as inductors, capacitors, etc at fractional light speed, where, presumably, mass and size change with velocity? w4mb



If you're traveling along with the component and make a measurement, then you'll see exactly the same component value as you do when you and the component are at rest.

When I figure out how to attach test leads to a resistor moving at

0.99c, then maybe the value in other frames will become of interest :-).

Hmm, quite a challenge. You'd have to coil up a few billion km of test lead in advance, and as it uncoiled at the speed of light, its inductance would be changing... it would be heck for AC current measurements. I suppose unspooling it that fast might make for a bit of triboelectric interference, too.

That helps explain why they use such darn strong springs in the little miniclips, though. Never could figure that out.

Duh! Relative to _what_? Think about it.

Not to mention that the red shift would turn the red test lead into a black one. The black test lead? Dunmo, maybe IR? :-P

HP did the experiment of taking one of their cesium clocks around the world on a plane while its twin stayed home. When reunited, the traveling clock was behind by the amount predicted under general relativity.
