See attached schematic.
Top transistors, TIP125, right is on, left is off.
Bottom right TIP120 is on. The coils are 7 ohms.
Bottom left is 10 parts in parallel. These 10 transistors are all off. The coils are 0.7 ohms because there are 10 in parallel.
Current, in red, flows from 24V through, TIP125 through the coil and via a TIP120 to ground. 24V on right coil.
Current, in red dots, flows down through 10 coils to the left transistor(s)-C, then up through 10 coils to the off TIP125-C.= 20 volts. You have 20 volts across the left coil.
To say it another way. The left coil has a current path that starts out with 0.7 ohm coil, 0.7 ohms coil, then a 7 ohm coil. The coil will be on at 20 volts.
