For example, eliminating dependence on the electrical grid is relatively simple but growing all necessary food is a more demanding and time-consuming proposition.

For example, a clock signal is subject to the delays of any other electrical signal.

For example, carbon can be found as diamond, which has a tetrahedral structure around each carbon atom ; graphite, which has layers of carbon atoms with a hexagonal structure stacked on top of each other ; graphene, which is a single layer of graphite that is incredibly strong ; fullerenes, which have nearly spherical shapes ; and carbon nanotubes, which are tubes with a hexagonal structure ( even these may differ from each other in electrical properties ).

For use in an electronic circuit, electrical connection terminals called taps are often connected to a coil.

For example, they may work on the design of telecommunication systems, the operation of electric power stations, the lighting and wiring of buildings, the design of household appliances or the electrical control of industrial machinery.

For example, quantum mechanics and solid state physics might be relevant to an engineer working on VLSI ( the design of integrated circuits ), but are largely irrelevant to engineers working with macroscopic electrical systems.

For large electrical demands electrical energy must be generated and transmitted continuously over conductive transmission lines.

For example, the development of the telegraph shortened the time taken to send a letter by transferring the letter as an electrical signal ( for example in Morse code ) between distant points.

** For ohm – SI unit of electrical resistance ; formerly also used upside down () to represent mho, the old name for the inverse of an ohm ( now siemens with symbol S ) used for electrical conductance.

For example, standby electrical power used in a household is not accurately known and varies between households, but is typically of the order of a few tens of watts.

For example, the rate at which a light bulb transforms electrical energy into heat and light is measured in watts — the more wattage, the more power, or equivalently the more electrical energy is used per unit time.

For example, if the user dials " 6 " on a North American phone, electrical contacts wired through the cam mechanism inside the phone will open and close six times as the dial returns to home position, thus sending six pulses to the central office.

For nearly a century, the electrical construction industry used the abbreviation " MCM " to designate a " thousand circular mils " in specifying thicknesses of large electrical cables.

For electrical and electronics work, a low-power iron, a power rating between 15 and 35 watts, is used.

For electrical and electronics work solder wire is available in a range of thicknesses for hand-soldering, and with cores containing flux.

For example, science might study the flow of electrons in electrical conductors, by using already-existing tools and knowledge.

For example, the Trade and Technician Skills Institute in Brisbane, ( from 1 July 2006 ), specialises in automotive, building and construction, manufacturing and engineering, and electrical / electronic studies for students throughout Queensland.

For example amine oxides, which are often written as R < sub > 3 </ sub > N < sup >+</ sup > O < sup >-</ sup >, are not zwitterions in terms of the definition, which specifies that there are unit electrical charges on atoms.

For example, the average power transmitted by an acoustic or electromagnetic wave or by an electrical signal is proportional to the square of the RMS amplitude ( and not, in general, to the square of the peak amplitude ).

For alternating current electrical power, the universal practice is to specify RMS values of a sinusoidal waveform.

For example, the term is used to describe systems such as verlan and louchébem, which retain French syntax and apply transformations only to individual words ( and often only to a certain subset of words, such as nouns, or semantic content words ).

For example, autopilot systems that are prolific today were started to help bomber planes fly steadily enough to hit precision targets from high altitudes.

For a time, the combined company retained the Burroughs processors as the A and V systems lines.

For example, an information systems specialist will view computing somewhat differently from a software engineer.

For example, programming language theory studies approaches to description of computations, while the study of computer programming itself investigates various aspects of the use of programming languages and complex systems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to humans.

For instance, NASA has extremely rigorous software testing procedures for many operating systems and communication functions.

For example, programming language theory considers various approaches to the description of computation, whilst the study of computer programming itself investigates various aspects of the use of programming language and complex systems.

For example, kinship and leadership function both as symbolic systems and as social institutions.

For very large systems, the relative total energies can be compared using molecular mechanics.

For π-electron systems, this was the Hückel method proposed by Erich Hückel, and for all valence electron systems, the extended Hückel method proposed by Roald Hoffmann.

For example, the conservation of energy follows from the time-invariance of physical systems, and the fact that physical systems behave the same regardless of how they are oriented in space gives rise to the conservation of angular momentum.

For some distributed parameter systems the vectors may be infinite-dimensional ( typically functions ).

For simplicity, the following descriptions focus on continuous-time and discrete-time linear systems.

For example, there is a hard disk, from which most operating systems run and on which most store their files.

For instance, on newer MS Windows computers, the older FAT-type file systems of MS-DOS and old versions of Windows are supported, in addition to the NTFS file system that is the normal file system for recent versions of Windows.

For continuous, frequent or prolonged intravenous chemotherapy administration, various systems may be surgically inserted into the vasculature to maintain access.

For example, Burris has reviewed sociological publications and used the theories of Weber and Bourdieu to describe academic caste systems.

For this reason it is not hard to port games between these systems.

For embedded systems, the highest performance levels are often not needed or desired due to the power consumption requirements.

For a while hybrid cable / electric systems operated, for example in Chicago where electric cars had to be pulled by grip cars through the loop area, due to the lack of trolley wires there.

For microscopic, atomic-level systems like a molecule, angular momentum can only have specific discrete values given by
