harmonics increase heating of motors ,Transformers and capacitors .Power system protecting relays may operate falsly, meters give inaccurate readings,interference with telephone lines may also occur.
Moreover resonance due to harmonics also causes problems

Is odd harmonics present in push pull amplifier?
Odd harmonics are theoretically the only harmonics that are produced by a push-pull amplifier, and even the level of odd harmonics should be very low.
Harmonics in three phase why not in single phase?
Harmonics are the result of the current waveform being distorted by a non-linear load, such as a computer power supply or a motor control drive (VFD). In a commercial setting (which is usually 3-phase), harmonics cause unwanted current to flow which does no useful work, yet must be accounted for when sizing conductors, transformers, etc. Harmonics are certainly not limited to 3-phase systems, however. Any non-linear load, even single-phase, causes harmonics. Your computer, television, and microwave oven probably create harmonics. In a residential setting though, there are not enough cumulative harmonic currents to worry about. Unless you have 50 computers at your house...
Determine second third and 12TH harmonic of a sine wave?
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.
What type of wave is square wave?
A square wave is the sum of all odd harmonics of the fundamental frequency.A sawtooth or ramp wave is the sum of all even harmonics of the fundamental frequency.
What will happen if two generators are running in parallel but having different winding pitch?
pitch windings are used to suppressed the harmonics. while operating two gen sets in parallel having different pitch windings will certainly cause problems in reducing the harmonics . for example a generator with pitch winding 2/3 suppressed the triple harmonics but may enhance the 5th and 7th harmonics similarly a generator with pitch winding 5/6 suppressed the 5th and 7th harmonics but may enhances the triple ones . so the act would counter act each other.
What guitar has the best harmonics?
There are no best harmonics.
When was Psy-Harmonics created?
Psy-Harmonics was created in 1993.
When did Sigma Harmonics happen?
Sigma Harmonics happened in 2008.
Is odd harmonics present in push pull amplifier?
Odd harmonics are theoretically the only harmonics that are produced by a push-pull amplifier, and even the level of odd harmonics should be very low.
What is the term for overtones that are multiples of the fundamental frequency?
They're called "harmonics".
When was Sigma Harmonics created?
Sigma Harmonics was created on 2008-08-21.
What are harmonics in power distribution system?
Harmonics are a multiple of the fundamental frequency. If the power frequency is 60Hz, harmonics occur at 120Hz, 180Hz, 240Hz, etc.
How can I improve my understanding and mastery of harmonics on the guitar?
To improve your understanding and mastery of harmonics on the guitar, practice regularly by experimenting with different harmonic techniques such as natural harmonics, artificial harmonics, and pinch harmonics. Study the theory behind harmonics and how they relate to the guitar's fretboard. Utilize resources like online tutorials, books, and instructional videos to deepen your knowledge. Additionally, listening to and analyzing music that features harmonics can help you develop a better ear for incorporating them into your playing.
Can you tell me about the different techniques used to play string harmonics on the cello?
String harmonics on the cello are produced by lightly touching the string at specific points while bowing, creating a higher pitch than the regular notes. Techniques include natural harmonics, artificial harmonics, and pinch harmonics. Natural harmonics are played by lightly touching the string at specific nodal points, while artificial harmonics involve using two fingers to create the harmonic. Pinch harmonics are created by plucking the string with the thumb while touching it lightly at a specific point.
When referring to sound waves what does harmonics mean?
Harmonics are multiples of the fundamental frequency of the wave.
Why harmonics present in a signal?
if a signal is not a pure sine wave it must contain harmonics
Why the need of harmonics in single phase transformer?
Harmonics are really not needed in single phase transformers.
