WebMay 16, 2016 · 5 Answers. The power dissipated in the wires is not reactive power, because the voltage drop in the wires is in-phase with the current through them. This is real power. If the load is purely reactive (a pure inductance or pure capacitance), the voltage across the load is 90° out-of-phase with the current, and so no real power is dissipated there. philly camera store
