 Ohm biography
Had Ohm's brothers and sisters all survived he would have been one of a large family but, as was common in those times, several of the children died in their childhood.
Ohm's father, angry that his son was wasting the educational opportunity that he himself had never been fortunate enough to experience, demanded that Ohm leave the university after three semesters.
Ohm had believed that his publications would lead to his receiving an offer of a university post before having to return to Cologne but by the time he was due to begin teaching again in September 1827 he was still without such an offer.

 Ohm   (Site not responding. Last check: 2007-10-31)
The 'ohm\' is the SI derived unit of electrical resistance (derived from the ampere and the watt).
The ohm is named for Georg Ohm, a German physicist who discovered the relation between voltage and current, expressed in Ohm's Law.
A measurement in ohms is the reciprocal of a measurement in siemens, the SI unit of electrical conductance.

 Ohm
Ohm’s law stated that the amount of steady current through a material is directly proportional to the voltage across the material, for some fixed temperature.
Ohm was afraid that the purely experimental basis of his work would undermine the importance of his discovery.
Ohm’s law of 1826 states that if the given temperature remains constant, the current flowing through certain conductors is proportional to the potential difference (voltage) across it.

He found that if the voltage across a conducting material is changed, the current flow through the material is changed proportionally (for example, if the voltage is doubled then the current also doubles).
If a current of I amperes flows between two points in a conductor across which the potential difference is V volts, then V/I is a constant called the resistance R ohms between those two points.

 Science Fair Projects - Comrie (crater)
Nearby craters of note include Ohm to the south-southwest, Shternberg to the southwest, and Parenago to the northeast.
Within the crater interior, a small crater lies near the northwest rim, a smaller crater just to the southwest of the mid-point, and a still smaller crater along the surviving southwest rim.
Streaks from the ray system of Ohm crater lie across the interior of Comrie crater, particularly in the western half.

 arjuno-welirang
The three craters within which the steam heated features occur are the three youngest craters on the volcanic complex forming a NNW-SSE trending line from the presently cold Arjuno crater in the south, through Kembar II and Kembar I, to G.Welirang in the north.
Although thesprings are fault controlled the temperatures would suggest that they are not fed from a deep hot water source and thus it is likely that the faults are only intersecting shallow outflows which may be mixed with surface meteoric water.
The main upflow zone is presumably directly below the craters and this may be difficult to tap due to the steep flanks of the volcano.

 Ohm - meaning of word
For the scientist, see Georg Ohm.'' The ohm is the SI SI derived unit of electrical resistance (derived from the ampere and the watt).
A measurement in ohms is the reciprocal of a measurement in siemens (unit), the SI unit of electrical conductance.
The ohm is since 1990 maintained internationally using the quantum Hall effect, where a conventional value is used for the 'Klaus von Klitzing constant', fixed by the 18th CGPM as R

Careful observations demonstrated that rays were centered on and extended from bright craters, had lengths proportional to their source crater's diameters, were discontinuous, crossed over high and low areas without deviation, and often contained tiny bright crater pits.
The reason rays were misinterpreted is that impact cratering was inconceivable, and thus so were the immense distances that rocks could be ejected during an impact.
One peculiar ray seems to extend from near the crater Cardanus, passes Seleucus crater, and skirts the northern end of the Aristarchus Plateau.

This high resistivity at shallow depth can be interpreted as uplifted basement rocks of the structural high in the centre of the crater.} \item{Between radial distances of 50 and 70 km is a zone of lower resistivities in the upper 5-10 km of the crust.
Marine seismic studies were conducted to investigate crater morphology (thickness of post-impact sediments, depth and shape of central uplift).

Laboratory studies and borehole logs show that kimberlite can have a wide range of electrical resistivity, from tens of ohm.metres to tens of thousands of ohm.metres.
Crater and diatreme facies rocks are generally more porous and susceptible to weathering, which tends to result in lower resistivities.
The hypabyssal phase rocks can also weather, but are less likely to do so and, due to their generally lower porosities, result in higher resistivities.

 PMPO Vs OHM value of speaker
You may choose to parallel speakers (8 ohms) to get more power out of your amplifier beacause of higher output current delivered to the total speakers, ofcourse if the specifications allow you to do so!(use 4 ohms speakers).
They are not related - each represents a different speaker feature: Impedance (Ohm) - most speakers are in the 4 or 8 ohm range (for household purposes) Max Power (W DIN or W PMPO) - maximum power beyond which speaker severely distorts sound, burns out, or disintegrates.
So, to get 100W in to our 8 Ohm spec we need to deliver a current of root(100/8) = 3.5A As I said, let's assume the amplifier is also spec'd a 100W in to 8 Ohms, but in practice can only support about 5% more than that should the need arise.
