"In a normal alternating current power system, the current varies sinusoidally at a specific frequency, usually 50 or 60 hertz. When a linear time-invariant electrical load is connected to the system, it draws a sinusoidal current at the same frequency as the voltage (though usually not in phase with the voltage). Current harmonics are caused by non-linear loads. When a non-linear load, s… " - Harmonics in single phase systems
