Discussion Topic

Discussion Question(s):

Superconductors are materials that can conduct an electric current with zero, or close to zero, resistance. Using
what you have learned about power in electric circuits, explain why so

many people are so interested in
superconductors. Include a discussion of two practical uses of superconductors and why superconductors are
better for those uses than regular conductors.

Discussion Could Focus On:

Magnetic shielding devices, medical i
maging systems, power transmission, superconducting magnets in
generators, energy storage devices, particle accelerators, levitated vehicle transportation

Possible Redirect(s):

The speed of computer chips is limited by the generation of heat and the ch
arging time of capacitors due to the
resistance of the interconnecting metal films. The use of new superconductive films may result in more densely
packed chips that can transmit information more rapidly by several orders of magnitude.

Concluding Quest

Superconductors hold great promise for modern technology. What prevents engineers from using them in more
practical applications?
