Capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance.However, they can be treated, to a very good degree of approximation, as being ideal capacitors and inductors in series with a resistance; this resistance is defined as the equivalent series resistance (ESR).
Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
"Magic" smoke being released from an electronic component for demonstration purposes. Magic smoke (also factory smoke, blue smoke, or the genie) is a humorous name for the caustic smoke produced by severe electrical over-stress of electronic circuits or components, causing overheating and an accompanying release of smoke. The smoke typically ...
Different keying for each colour in the SB50 series. Note that black and grey are keyed the same making them interchangeable. For the larger multipole design, which is available in up to 700 A sizes, each color is physically keyed so as to mate only with a like colored connector, and Anderson published a list of recommended voltage for each color:
Voltage-controlled resistors are one of the most commonly used analog design blocks: adaptive analog filters, [1] automatic gain-control circuits, clock generators, [2] compressors, [3] electrometers, [4] energy harvesters, [5] expanders, [6] hearing aids, [7] light dimmers, [8] modulators (mixers), [9] artificial neural networks, [10] programmable-gain amplifiers, [11] phased arrays, [12 ...
In electronic design and power transmission, various techniques are employed to compensate for the effect of voltage drop on long circuits or where voltage levels must be accurately maintained. The simplest way to reduce voltage drop is to increase the diameter of the conductor between the source and the load, which lowers the overall resistance.
A line-level attenuator has lower power handling, such as a 1/2-watt potentiometer or voltage divider and controls preamp level signals, whereas a power attenuator has higher power handling capability, such as 10 watts or more, and is used between the power amplifier and the speaker.

Between 2007 and 2012, EBOX, formerly known as Electronic Box, increased its net sales by 1,859%. [2] Following a decision from the CRTC in 2011 favoring Canadian independent telecom service providers, Electronic Box was one of the first independent providers to offer Internet services at a reduced rate.
