Answer:
Harmonics
Step-by-step explanation:
Harmonics are unwanted higher frequencies which superimposed on the fundamental waveform creating a distorted wave pattern. In an AC circuit, a resistance behaves in exactly the same way as it does in a DC circuit. That is, the current flowing through the resistance is proportional to the voltage across it. A harmonic is any member of the harmonic series. The term is employed in various disciplines, including music, physics, acoustics, electronic power transmission, radio technology, and other fields. It is typically applied to repeating signals, such as sinusoidal waves
