Harmonics are integral multiples of some fundamental
frequency that, when added together, result in a
distorted waveform.Harmonic currents and voltages are created by non-linear
loads connected on the power distribution system.
Harmonic distortion is a form of pollution in the electric plant
that can cause problems if the sum of the harmonic currents
increases above certain limits.

What are harmonics in a complex waveform?
Scroll down to related links and look at "Calculations of Harmonics from Fundamental Frequency".
What is the reason of harmonics in transformer and induction motor?
To be very brief, Harmonics are caused because of magnetising current flowing in the primary of transformer, which cause deaviation from the ideal sinusoidal waveform producing peaky currents in the primary. Due to this the core of the transformer gets saturated and the wave form produced in the secondary also gets distorted.
Sources of harmonics?
Harmonics is multiple of fundamental frequency. Spurious is not related to fundamental frequency but it is observed at the output spectrum. Harmonics are generated due to non-linearity of the device. Harmonics can generate spurious. As an example harmonics can produce resonance with mechanical box internal structure and can generate spurious. Harmonics generally generated from TCXO & frequency multipliers. If amplifier is non-linear, this will also generate harmonics. But harmonics very near to carrier generally generates interference to modulating signals. We design final power amplifier as a class AB amplifier to get more output power and better efficiency and also to minimize output power variation with temperature. Since it is non linear amplifier it generates harmonics but it will be very far from carrier and can be filtered easily. See the link for detail :- http://harshit.org/spurious and harmonics.pdf
Why even harmonics are not present in push pull amplifier?
Symmetrical push/pull circuits must cancel even ordered harmonics, like f2, f4, f6 and therefore promote odd ordered harmonics, like (f1), f3, f5 when driven into the nonlinear range.
Why is there a harmonics when there is no load?
Harmonics is electric current or voltages that are part of the power system as a result of nonlinear electric loads. If there is no load and a harmonic is present it can present because of a rectifier in the system.
How are unwanted harmonics produced?
unwanted harmonics are produced when your finger slides over a reactive note after a single note
What are harmonics in music?
Harmonics in music are notes which are produced in a special way. They are notes which are produced as part of the "harmonic series".
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 harmonics are produced in a tube that is closed at one end?
In a tube closed at one end, only odd harmonics are produced. This is because the closed end acts as a node for the pressure wave, leading to a fundamental frequency and odd harmonics of that frequency.
What is produced when overtones have frequencies that are whole number multiples of the fundamental?
That are harmonics: fundamental + overtones. Calculations of harmonics from fundamental frequency. Look down to the related links: "Harmonics Calculator".
Produced by vibrations that are multiples of the fundamental frequency?
These are known as harmonics, or overtones.
What information can I find on a guitar harmonics chart?
A guitar harmonics chart provides information on where to find natural and artificial harmonics on the guitar fretboard. It shows the specific frets and strings where harmonics can be produced, allowing guitarists to create unique sounds and effects while 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.
What is the relationship between string harmonics and the production of sound in musical instruments?
String harmonics are specific frequencies produced when a string vibrates in segments, creating a higher pitch. These harmonics contribute to the overall sound of a musical instrument by adding complexity and richness to the tone.
Plucking the string on a violin or cello is called?
These are called "harmonics" there are different kinds of harmonics, Natural, and Pinch are the only ones i could name. natural harmonics are simple. pinch harmonics are a bit tricky though. hope this helps.
What is the significance of harmonics in the vibration of a piano wire?
Harmonics in the vibration of a piano wire are important because they determine the tone and timbre of the sound produced. When a piano wire vibrates, it creates multiple harmonics, which are higher frequency vibrations that occur in addition to the fundamental frequency. These harmonics give the piano its unique sound and richness, allowing for a wide range of musical expression.
What are natural harmonics and how do they contribute to the overall sound of a musical instrument?
Natural harmonics are specific tones produced by a musical instrument when a string is lightly touched at certain points. These harmonics create additional frequencies that blend with the fundamental tone, enriching the sound and adding complexity to the overall timbre of the instrument.
