Figures 16, 17, 18. — Equivalent n of line imitated in Figures 5, 6, and 7. 

 Grounded, freed, and grounded imperfectly. 



Thus, with r" = 4044.2 ohms, and R" = 2034.05 ohms, as in Figures 

 16, 17, and 18, we have tanh = V4044.2/81 12.3=0. 70606, and r = 

 2034.05 X 0.70606 = 1436.1 ohms, as before.
