ductance. 48. In equations (11) to (14) s is the distance between the con-ductors. If s is large compared with r, it is immaterial whetheras s is considered the distance between the conductor centers, orbetween the insides, or outsides, etc.; and, in calculating the in-ductance of transmission-line… … AFig. 69. — Inductance Calculation of Cable. However, if s is of the same magnitude as r, as with the con-ductors of cables, the meaning of s has to be specified. Let then in Fig. 69 r = radius of conductors, and s = distancebetween conductor centers. Assuming uniform current densityin the…
