Question:
Do super conductors have zero resistance for both AC and DC? What is the November 2007 (no pun) highest temperature for a super conductor wires?


Replies:
Steve,

Superconductors have no resistance at all, so it's true they'll have none for either AC or DC. However, inductance is another matter, so under the correct conditions, AC may still have some losses. I do not know the current (2007) highest temperatures achieved on superconductors, so I cannot help you there.
