Question

Because high-temperature superconducting cables cannot sustain high currents, their applicability is limited. However, a prototype of a high-temperature superconductor that can transfer a charge of 1.8 x 10^5 C in 6.0 min has been constructed. To what current does this correspond?

Answer 1

I = Q/t [C/sec]
I = 1.8x10⁵ /(6*60) = 500 A.
