Harmonics
(OP)
Can someone please describe to me the effects of harmonics on single-phase measurements, especially in circuits containing reactive components

RE: Harmonics
Reactances of coils and capacitors are frequency dependant. Coil reactance increases whith frecuency while capacitor reactance decreases, in sucha a way that a circuit having both types of elementes behaves diferently for every component of distorded wave.
For example: a distorded current flowing through an inductance produces a voltage drop much more distorded than current and vice versa: a coil connected to a distorded voltage source wants a less distorded current.
On the other hand capacitors have an opposite performance: current is a much more distorded than voltage.
Many of these harmonic components do not produce usefull work but increase RMS values of currents or voltages reducing the power phactor and increasing losses.
