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 electrical systems which use alternating current the electrodes are the connections from the circuitry to the object to be acted upon by the electric current but are not designated anode or cathode since the direction of flow of the electrons changes periodically, usually many times per second.

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 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 security, the AMS used a media block type system that placed a sealed electronics package within the projector console.

For instance, early electronics often used point to point wiring with components attached to wooden breadboards to construct circuits.

For example, cellphones, personal digital assistants and other consumer computers often need significant software that is purchased or provided by a person other than the manufacturer of the electronics.

For electronics, one farad is a fairly large amount of capacitance.

A Li-Polymer battery with a hard case is most popular for RC cars, with the most common voltages being 7. 4 V or 11. 1 V. For nitro-powered vehicles, a glow plug heater and fuel are needed to start the engine, as well as 4 AA size batteries, or a rechargeable 6-volt 5-cell battery pack to power the onboard electronics.

For electronics hobbyists the parallel port is still often the easiest way to connect to an external circuit board.

For example, with radiographic equipment such as a CT scanner, one would reasonably require the operator to have competence in radiological safety ; but for consumer electronics, the goal ( distant as it often may be ) is to shield the user from having to possess any arbitrary threshold of skill.

For few categories, such as electronics, the products are displayed at the centre of the store and sales person will be available to address customer queries and give suggestions when required.

For critical electronics applications a linear regulator may be used to set the voltage to a precise value, stabilized against fluctuations in input voltage and load.

For those who are looking for electronics and accessories, the Apliu Street market is well known in Hong Kong.

For example, it is the parallel-resistance formula in electronics, and the thin-lens equation in optics.

For example, it is speculated that the F-22 is able to jam or damage enemy electronics with a focused application of its radar.

For sensitive electronics, excessive current can flow if this voltage spike exceeds a material's breakdown voltage, or if it causes avalanche breakdown.

For semiconductor devices used in a variety of consumer and industrial electronics, the idea of thermal resistance simplifies the selection of heat sinks.

For example, a refrigerator may be made more efficient by the use of more insulative spacing and a smaller-capacity compressor using electronics to control operation and temperature.

For more than thirty years, EE Times has been the electronics industry newspaper of record for design and development engineers and technical managers.

For radar dishes, a single, large, ball-shaped dome also protects the rotational mechanism and the sensitive electronics, and is heated in colder climates to prevent icing.

For those builders who had a deeper knowledge of electronics ( or for those who wanted to be able to troubleshoot / repair the product in the future ), the assembly manuals usually included a detailed " Theory of Operation " chapter, which explained the functioning of the kit's circuitry, section by section.

For instance, tunnelling is a source of current leakage in very-large-scale integration ( VLSI ) electronics and results in the substantial power drain and heating effects that plague high-speed and mobile technology ; it is considered the lower limit on how small computer chips can be made.

For applications outside the realm of high speed electronics, long ( compared to the attainable state of the art ) rise times are sometimes desirable: examples are the dimming of a light, where a longer rise-time results, amongst other things, in a longer life for the bulb, or digital signals apt to the control of analog ones, where a longer rise time means lower capacitive feedthrough, and thus lower coupling noise.

For major channel crossings, most organizations do allow the swimmer to use outside help, an example being that the swimmer swims alongside a boat that uses sophisticated electronics and telecommunications to help the swimmer take the easiest path through surface currents and tides.

" For 25 years, Putnam headed the bureau and during his administration, navigational aids saw a substantial increase and new technology was incorporated into the bureau's work, particularly in the area of electronics.

For radio frequencies, this is possible by electronics, while for optical lights, the electromagnetic field cannot be measured directly and correlated in software, but must be propagated by sensitive optics and interfered optically.
