A 20-kHz high-power cable has a 10-mm conductor diameter. Determine its approximate R ac /R dc ratio

Question:

A 20-kHz high-power cable has a 10-mm conductor diameter. Determine its approximate R_ac/R_dcratio if it is (1) Made of one solid conductor,

(2) Made of numerous thin conductor strands that are not insulated from each other, and

(3) Made of Litz cable. Use the concept of skin depth in your calculations and explain the reason why a Litz cable gives the best results at such high frequency.
