Reactive power and power factor correction essentials to
2019/9/2 2. The effects of low power factor. There are two main problems associated with low power factor (or the presence of reactive power) in a load: Voltage drop; Efficiency (and cost of energy supply) 2.1 Voltage Drop. The reactive component of current, I × sinφ, causes unwanted voltage drop that affects the regulation at the load.

Sources and Causes of Low Power Factor - Electrical Technology
There are several causes of low power factor, including: Inductive Loads: Inductive loads, such as electric motors and transformers, consume reactive power from the system, which reduces the power factor (lagging PF).This is because inductive loads cause the voltage and current to become out of phase, which increases the reactive power component of the system.

How does a Low Power Factor draw more current?
2017/10/14 If the power factor were 0.9, and the power supply gives 110V, we would need 10A. If the power factor were 0.6, and the power supply gives 110V, we would need 15A. However, something here just doesn't make sense. If we consider the power supply as an ideal voltage source, then the current has nothing to do with the given power.
