Ohm

The ohm (symbol: Ω) is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm. Although several empirically derived standard units for expressing electrical resistance were developed in connection with early telegraphy practice, the British Association for the Advancement of Science proposed a unit derived from existing units of mass, length and time and of a convenient size for practical work as early as 1861. The definition of the ohm was revised several times. Today the definition of the ohm is expressed from the quantum Hall effect.

Definition

The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere, the conductor not being the seat of any electromotive force.

in which the following units appear: volt (V), ampere (A), siemens (S), watt (W), second (s), farad (F), joule (J), kilogram (kg), metre (m), and coulomb (C).

OHM (band)

OHM (sometimes stylized Ohm: or OHM:) is an American instrumental rock/jazz fusion group fronted by former Megadeth guitarist Chris Poland. The band was formed in 2002 and has released three studio albums and a live album. A similar offshoot band named OHMphrey, also fronted by Poland, was formed in 2008.

The band often perform at the Baked Potato jazz club in Studio City, California.

Ohm (crater)

Ohm is a lunar impact crater that is located on the far side of the Moon. It lies to the south of the crater Comrie, and the satellite crater Comrie K is attached to Ohm's northeastern rim. To the northwest is the larger Shternberg, and to the southwest is Kamerlingh Onnes.

This crater is located at the origin of an extensive ray system that extends for several hundred kilometers across the surrounding lunar terrain. The exterior surface for about 20–30 km is relatively free of the ray material, but beyond that perimeter is a skirt of higher albedo, with streaks extending to the northwest, east-northeast, and southwards. The crater is part of the Copernican System.

The outer rim of Ohm is sharply defined, except at the southern end where the edge is somewhat irregular. The inner surface drops down to an interior blanket of slumped material that slopes down to the floor. The crater lacks a notable central peak.

Unit of alcohol

Units of alcohol are used in the United Kingdom (UK) as a measure to quantify the actual alcoholic content within a given volume of an alcoholic beverage, in order to provide guidance on total alcohol consumption.

A number of other countries (including Australia, Canada, New Zealand, and the US) use the concept of a "standard drink", the definition of which varies from country to country, for the same purpose. "Standard drinks" were referred to in the first UK guidelines (1984) that published "safe limits" for drinking, but these were replaced by references to "alcohol units" in the 1987 guidelines and the latter term has been used in all subsequent UK guidance.

One unit of alcohol (UK) is defined as 10 millilitres (8 grams) of pure alcohol. Typical drinks (i.e. typical quantities or servings of common alcoholic beverages) may contain 1–3 units of alcohol.

Containers of alcoholic beverages sold directly to UK consumers are normally labelled to indicate the number of units of alcohol in a typical serving of the beverage (optional) and in the full container (can or bottle), as well as information about responsible drinking. Additionally, the advent of smartphones has led to the creation of apps which report the number of units contained in an alcoholic drink.

Military organization

Military organization or military organisation is the structuring of the armed forces of a state so as to offer military capability required by the national defense policy. In some countries paramilitary forces are included in a nation's armed forces, though not considered military. Armed forces that are not a part of military or paramilitary organizations, such as insurgent forces, often mimic military organizations, or use ad hoc structures.

Military organization is hierarchical. The use of formalized ranks in a hierarchical structure came into widespread use with the Roman Army. In modern times, executive control, management and administration of military organization is typically undertaken by the government through a government department within the structure of public administration, often known as a Ministry of Defense, Department of Defense, or Department of War. These in turn manage Armed Services that themselves command combat, combat support and service support formations and units.
