For a Romex equivalent ballast, try this:

 

Leave wire on spool,

Strip end #1 of black wire and attach to your circuit,

Strip end #2 of black wire and end #1 of white wire, connect these together
(in series).

Strip end #2 of white wire and attach to the other side of your circuit.

 

The inductance will be additive.

Your net inductance will equal = Lblack + Lwhite + Lmutual = Ltotal

 

Just watch your total voltage drop across the series coil.

 

Note: Romex AC wire is rated 300 or 600 volts, depending on the supplier,
where speaker wire is only rated for 50 or 150 volts.

 

 

But, If you:

 

Leave wire on spool,

Strip end #1 of black wire and attach to your circuit,

Strip end #1 of white wire and attach to the other side of your circuit,

Strip end #2 of black wire and end #2 of white wire, connect these together
(in parallel)

 

The inductances will cancel, leaving just pure resistive wire. This is
called bifilar winding.

Your net inductance will equal = Lblack - Lwhite = Ltotal = 0
