Seems correct but can you don't add L and R also with another function, all 3 in a single class???

Ok but Resistors don't affect reactive power inductors and capacitors do
i will add L and C in one class

For R, to correct the power factor of a load with an undesired resistance, I think u need to add a parallel shunt resistor, its calculation will involve the real power and resistance.

It's been 2 yrs since I don't touched electrical engineering, so correct me if I goes wrong somewhere.

Thats possible sir
but power factor correction is needed without affecting the real power absorbed by the load adding a resistor affects amount of power the load absorbs i haven't seen a use case that uses a resistor to correct power factor
so capacitor is used if load is lagging (inductive)
inductors used when the load is leading (capacitive)
in both cases we must approach the pf to unity by adding the respective element(power factor correction) without altering the real power absorbed by the load
i will create an inductor one and add additional examples and checks
