superconductor question


Recommended Posts

I understand that in a normal conductor, the electron going in at one end of a wire will take a long time to get to the other end, and was wondering if the same thing applied to superconductors also, or do the cooper pairs pass more quickly or even at c ?...

I have a related question as to charge mobility of conductor vs. superconductor.... Is there any charge speed difference observed in the two materials?

Resistance to flow affects quantity not velocity. The impulse of the electron motive force travels at relative velocities.

Think of it this way, a hose is full of water, if we force a cup of water into one end, almost immediately a cup will exit the other end. If we stop adding water the cup we forced in will never make it out, but the impulse of that force had an effect on the opposite end much faster than water could ever travel through the hose.

Theoretically superconductors have no resistance...

Ohms law states that current = voltage/resistance.

Division by 0 says any voltage applied will result in infinite current, this of course is not possible, but you get the idea.
