When applied to electrical waveforms, a 'harmonic' is a multiple of the fundamental frequency.
A harmonic mean is a type of measure of central tendency calculated as the reciprocal of the mean of the reciprocals.
Total harmonic distortion is a measurement of harmonic distortion in an object and is the percentageÊof the powers of all the harmonic components of the object. The THD of a diesel generator is between 15% and 20%.

It depends on the frequency in the expression of the function. A third harmonic would mean that the frequency is 3 omega, thus the circuit will consist only of the quantities that have 3 omega in the expression. For example if you have : e(t)=5sin(3ωt+π/4) and is(t)=7sin(ωt+π/4), in the first harmonic the e(t) quantity will disappear from the circuit while in the third harmonic the is(t) quantity will be neglected.
Total Harmonic Distortion is an important phenomenon while selecting a UPS. AC Harmonic content (THD-Voltage) shall be <= 3% for linear load and <=5% for non linear load.
harmonic filter capacitor is used to filterize the unwanted heat created by a certain component like power supply. harmonics are voltage or currents that operates a certain frequency. john
Harmonic balancer is bad and will need to be replaced.
A motion is simple harmonic if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean position.
The advantage of harmonic mean is that it is used to solve situations in which there are extreme data values to true picture. The disadvantage of it is that it can be time consuming to evaluate the data.

A body undergoes simple harmonic motion if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean. Provided the amplitude is small, a swing is an example of simple harmonic motion.
If x and y are two positive numbers, with arithmetic mean A, geometric mean G and harmonic mean H, then A ≥ G ≥ H with equality only when x = y.
Music played in a harmonic, chordal texture.
Velocity is maximum at mean position for particle performing simple harmonic motion. Another feature that is maximum at this position is kinetic energy.
The arithmetic mean, geometric mean and the harmonic mean are three example of averages.
The geometric-harmonic mean of grouped data can be formed as a sequence defined as g(n+1) = square root(g(n)*h(n)) and h(n+1) = (2/((1/g(n)) + (1/h(n)))). Essentially, this means both sequences will converge to the mean, which is the geometric harmonic mean.
