Single Coil ohms -vs- Dual Coil ohms on the New Subtank RBA.

[BEast13]

If you have a simple, single coil that reads .5, and you add another one so that it is 2 of the exact same .5 simple coils, would it read at about 1 ohm or am I just not getting it? (Both are A1 Kanthal)

Thank you,

[UncleRJ]

If both coils are identical with the same leg length and each coil on its own reads 0.5 ohms, when both coils are installed the combined reading should be at 0.25 ohms.

 

[State O' Flux]

To extend Uncles concise answer a bit further... with multi-parallel coil builds, the net resistance is that of one coil, divided by the number of coils. Example: Five 1.0Ω coils ÷ 5 = 0.20Ω net resistance.
