__________ are load types where the load impedance is not constant.

Question

Quizplus · Accepted Answer

Non-linear loads, such as electronic devices and LED lighting, have a variable impedance that changes based on the voltage and current waveform, resulting in distortion and harmonics in the power system. Harmonics (A) are a type of distortion caused by non-linear loads, but they are not load types themselves. Linear loads (B) have a constant impedance and do not cause distortion or harmonics. True RMS (D) is a method for accurately measuring AC voltage and current regardless of waveform shape, but it is not related to load types.
