no power
If both sides of a light bulb is connected to the same side of the supply, the light bulb will:
not turn on

There are 10 diagrams to complete. Simplify all diagrams into another one with the live on the left and neutral on the right.
Drawing wiring diagram
Drawing wiring diagram
E.g. This circuit has 1 lightbulb (C) connected to light wire.
Anything connected to live/neutral wire directly goes to their respective vertical wire, never with a junction in between.
This circuit has many neutral connections.
Dots indicate junctions.
Now draw all lights connected to the neutral wire.
Here, Lightbulb A, B, D connect straight to neutral.
Light D had neutral on both side so both go to neutral. And Lightbulb C connects to neutral.
Note: All lines from components are best to be horizontal.
We highlighted all wires connected in the diagram.
Only A and B are left to be connected (in blue), called an interconnecting wire.
interconnecting wire: a line representing a wire connecting 2+ components
Connect Lightbulb A to B
And make all wires neater.
Installing lightbulbs
Installing lightbulbs
Label 5 identical low-voltage lightbulbs in order (A, B, C, D, E).
Note: It's best to connect a wire at a time.
What's goes to live wire goes to the disconnect's black terminal.
What's goes to neutral wire goes to the white terminal.

Instruction must be clear like:
1. Connect the disconnect's live wire to a side of C." (choose a side)
2. Connect the disconnect's neutral wire to C's other side.
3. Connect neutral to A.
4. Connect A's other side to B.
5. Connect B's other side to neutral.
6. Connect neutral to D.
7. Connect neutral to D's other side.
When connections are done, turn on the power to see which lightbulb is the brightest, which should match your predictions.
There are 9 more circuits to do.
