Superconductors and Conductors: Connections and Possibilities

AI Thread Summary
Superconductors can be connected to normal conductors in electric circuits without significant issues, as superconductors simply exhibit very low resistance. The main concern arises when transitioning from a superconductor to a conductor, where potential problems like overheating or space charges may occur. Generating current in a superconductor without an initial voltage applied to the conductor raises questions about circuit behavior. Additionally, the possibility of creating a power source with no internal resistance using superconductors is a topic of interest. Further exploration of circuit designs and resources is encouraged for a deeper understanding.

Greetings !

I was wondering how (or if) a superconducor can be
connected to a "normal" conductor in an electric
circuit ? I guess the conductor-superconductor connection
is easy, but how do you avoid problems at the reverse
connection - do you need some amplifier or something.

Also, what would happen if the current was generated in the
superconductor, and no enitial voltage is applied to the conductor ?

Thanks ! :smile:
 
Engineering news on Phys.org
The superconductor is just another conductor, it just happens to have very low resistance.
 
So there're no special problems - space charges/overheating
in the connections (beyond the standard) ?

Thanks.
 
drag,
The last site that you linked for me had a little discussion about that. Maybe you're looking for more detail. It spoke of the internal resistance of the voltage source and a switch that could be closed that would have a slight resistance. I can't remember what that link was off the top of my head.

Here it is:

Yeah, thanks, I read that, I just wanted a bit more info -
if anyone got some good links or something on actual circuits.

Also, I should've said that first too - I was wondering if it's
possible to make a power source with no internal
resistence by using a superconductor ?

Thanks. :smile:

Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
