| Coil with one of my Roentgen tubes as described in articles E.R. | |
| $! {36 \over 2} $! = 18 bottles = 0.0162 mfd | 5 1/8 turns + conn. |
| 5. | |
| Coil with âdouble focus tubeâ target connected. | |
| $! {36 \over 2} $! = 18 bottles = 0.0162 mfd | 5 1/16 turns + conn. |
| 6. | |
| Coil with same tube one of the electrodes connected. | |
| $! {36 \over 2} $! = 18 bottles = 0.0162 mfd | 5 3/32 turns + conn. |
| * Note: all of these tubes developed rays fairly strong while tested. | |
| 7. | |
| Coil with Leonard tube single terminal as described by me E.R., poorly exhausted, streamers passing through it. | |
| $! {36 \over 2} $! = 18 bottles = 0.0162 mfd | 5 turns + conn. |
From these measurements the capacities can now be found.
Calling the inductances in the primary circuit in each succeeding experiment respectively L1, L2, L3, L4, L5, L6 and L7 we have with reference to prepared table:
| L1 = 4 13/16 turns + conn. = 14,526 cm. L2 = 4 15/16 " + conn. = 14,947 " L3 = 4 31/32 " + conn. = 15,053 " L4 = 5 1/8 " + conn. = 15,579 " L5 = 5 1/16 " + conn. = 15,368 " L6 = 5 3/32 " + conn. = 15,473 " L7 = 5 " + conn. = 15,158 " |
Calling furthermore the corresponding capacities of the excited system Cs1....Cs7 all of them can be at once determined from Cs1 since Cs2 = $! {L_{2} \over L_{1}} $!Cs1 Cs3 = $! {L_{3} \over L_{1}} $!Cs1, etc. |
