Real Power or Reactive Power in Superconducting Motors?

My circuits class is teaching that in AC power, there are two kinds of loads. One is a resistive load, with absorbs power at all times. The other is a reactive load, which absorbs zero average power. ...

Does the formula v=Ldi/dt apply to materials with zero resistence, such as superconductors?

I've been trying to find information about the formula \$ v = L \cdot \frac{di}{dt} \$, it seem to have something to do with voltage drop, and I know voltage drop is caused by resistance, so would a ...

What will be the behaviour of superconductors if they are used as core or coil?

Superconductors are strong diamagnetic in nature so if they are used as core of any coil do magnetic lines of forces pass through them – I mean inside them just as with a soft iron core? Secondly if ...

What is the most available high-temp superconductor for samples and study?

I could only find one named Amperium on the web, but not on the eBay or any little shops. It is very interesting material with conductivity 40 times better than copper. Is it possible to buy anywhere ...
