Cesare, Thank you for your timely proximity equation! I calculate the spacing required to keep the proximity loss at 10% for two #12 ga (2.0 mm) copper conductors to be 0.5 inches. The spacing requir
Reff / Rrf = 1 + (q - 1) * SQR (( p - 1 ) / p ) This info is interesting! Question: Is SQR "squared" or "square root" ? In some programming languages SQR (X) = X^0.5, in others SQR (X) = X^2 while S
