double CurrentFromWidth(double aWidthMils, double aThicknessMils, double aDeltaT_C, bool aUseInternalLayer)
Compute the maximum current a track can carry for a given temperature rise.
double WidthFromCurrent(double aCurrentA, double aThicknessMils, double aDeltaT_C, bool aUseInternalLayer)
Compute the track width required to carry a given current for a given temperature rise.
