When connecting resistors in Parallel, THEN combined resistance does not sum but instead REDUCES in value (two same R-value divide by 2 & three same R-value divide by 3, etc). Parallel resistors Do sum their Wattage rating, but not their resistance values, their combined R value shall Always be Less than the smallest-value resistor of the combo. OTOH Series-connected resistors Will sum their R-values but Not their wattage ratings (which will only be what individual resistors are rated). He needs to re-visit the combined resistance formulas also present in Weems' Little Red Book.
