will also equal 16 ohms, Yep, if you are using regular wirewound power resistors, vs. the NON INDUCTIVE mills brand he mentioned. Building a 16 ohm part with the values available means they need to use the four 16 ohm ones, arranged as specified previously.resistors in series
Rt = R1 + R2 + R3+...
resistors in parallel
1/Rt = 1/R1 + 1/R2 +...
Hope the formulas make this clearer. Sam
