A resistive component converts electrical energy directly into heat, following Ohm's law where voltage and current are perfectly in phase. Unlike inductive or capacitive elements, a purely resistive load does not introduce phase shifts or frequency-dependent reactance. Engineers look for resistive behavior to simplify power calculations or when designing dummy loads for testing.
The load is mostly resistive, so we don't need to worry about power factor correction on this board.
