A 'resistive' load is one which results in a load current that is in phase with the supply voltage. There is no such thing as a 'purely resistive' load, as all practical loads will have some degree of inductance or capacitance, which will result in a very small lagging or leading phase angle. Typical resistive loads are heating elements in water heaters, etc.
A 'reactive' load is one which results in a load current that either lags (inductive) or leads (capacitive) the supply voltage. Purely reactive loads will result in a 90-degree lead or lag but, again, there is no such thing as a purely reactive load as all loads will have some degree of resistance. Accordingly, most reactive loads result in load currents which lag or lead the supply voltage by angles up to just short of 90 degrees.
A purely-resistive load would result in true power only; a purely-reactive load would result in reactive power only. Resistive-reactive loads would result in apparent power -a combination (vectorial sum) of true and reactive power.
When using a resistive load bank to test a generator, it does not matter if you load the generator to its kW or kVA rating, because those two numbers are the same when considering a resistive load. Power factor, which is the difference between true and apparent power, only comes into play when there is a reactive (inductive or capacitative) load.
It really does depend upon what you mean by 'shift'. For purely-resistive circuits, the load current is in phase with the supply voltage. For reactive circuits, the load current will lead or lag the supply voltage; for capacitive-resistive circuits, the load current leads, whereas for inductive-resistive circuit, the load current lags. You can change the angle by which the current leads or lags (the 'phase angle') by changing the amount of resistance or reactance.
You use power factor when the load is not resistive, i.e. when it is reactive, and the phase angle between voltage and current is not zero.
The 'type' of power is determined by the load. If the load is resistive (e.g. a lamp) then the rate at which it consumes energy is termed 'true power', expressed in watts.You seem to be under the impression that reactive power is 'pushed out' into a load. This is quite false; the loaddetermines the power.
You may be fishing for the answer "AC" or "alternating current", sinceno reactive component of power is developed in response to DC.AnswerSince true power (in watts) is associated with resistive components, and reactive power (in reactive volt amperes) is associated with reactive loads, the vector-sum of these is called apparent power (in volt amperes). So the answer you are looking for is apparent power.
A purely resistive load would indicate whatever watts would be normal for that load. A purely reactive load would indicate zero on the watt meter, in the theoretical case, because the power factor would be zero.

It does not matter, when testing a generator with a resistive load bank, if you load it to kVA or KW. For a resitive load, i.e. non-reactive load, the power factor is one, so kVA and kW are the same.
when a resistive load is applied there is no phase angle difference between voltage and current. when a inductive load is applied there is phase difference between voltage and current. current lags voltage by an angle of 90 degrees for pure inductive load

It is resistive much load
Its actually inductive, because the energy being used is to turn motors. Motor are an inductive load, so the end load is reactive. Do your own research so you will know how to apply it someday.
Unity power factor has a value of 1.0. This means the current and voltage waveforms are in phase. This is only possible if the net load is non-reactive (resistive). If the load is either capacitively or inductively reactive, the power factor will be other than unity. If an inductively reactive load such as a motor is offset by a capacitively reactive load such as a PF correction capacitor, it is possible to acheive a net load that has unity power factor. Some loads, such as resistance heaters, are intrinsically non-reactive, and present a unity power factor.
resistive loadAnswerIf the current is driving a motor, then the load is resistive-inductive.
You use power factor when the load is not resistive, i.e. when it is reactive, and the phase angle between voltage and current is not zero.
