SUMMARY
The discussion focuses on the process of assigning dots to coils in electrical circuits, specifically in relation to transformer dot conventions. The correct placement of dots is determined by the direction of the conductor's entry and exit from the core. For the left-hand coil, the dot is placed at the top where the conductor exits, while for the right-hand coil, the dot is also at the top. The bottom coil's dot is positioned to the right, indicating the exit direction of the conductor.
PREREQUISITES- Understanding of transformer dot conventions
- Basic knowledge of electrical circuits
- Familiarity with coil orientation in transformers
- Knowledge of conductor entry and exit points in magnetic cores
- Study transformer dot convention rules in detail
- Learn about magnetic core configurations in transformers
- Explore circuit analysis techniques for transformers
- Investigate the impact of dot placement on circuit behavior
Electrical engineers, students studying circuit design, and anyone involved in transformer design and analysis will benefit from this discussion.

Solution in the spoiler:
I don't know how to do the problem (a), but I also don't understand the answer (top of coil 3?). Can you give me the process on how to do the problem (a), i.e. in general how do I assign dots to coils in circuits? :)
the answer was wrong, it should be right side for coil 3, after finding that out i understand.

Assume that the conductor enters the core from the back and exits the core from the front.
Put a dot where the conductor exits the core.
On the left hand coil the conductor exits the core on the top. (It enters the core on the bottom.
On the right hand coil the conductor exits the core on the top. Put a dot at the top of the right hand coil.
On the bottom coil the conductor exits the core on the right. Put a dot to the right of the bottom coil.
Put a dot where the conductor exits the core.
On the left hand coil the conductor exits the core on the top. (It enters the core on the bottom.
On the right hand coil the conductor exits the core on the top. Put a dot at the top of the right hand coil.
On the bottom coil the conductor exits the core on the right. Put a dot to the right of the bottom coil.
