  • Electric transmission networks are interconnected into regional, national, and even continent wide networks to reduce the risk of such a failure by providing multiple redundant, alternative routes for power to flow should such shut downs occur. (wikipedia.org)
  • Thicker wires would lead to a relatively small increase in capacity due to the skin effect (which causes most of the current to flow close to the surface of the wire). (wikipedia.org)
  • circuit

  • As the amount of thermal noise generated depends upon the temperature of the circuit, very sensitive circuits such as preamplifiers in radio telescopes are sometimes cooled in liquid nitrogen to reduce the noise level. (wikipedia.org)
  • In electronic circuit theory, a "ground" is usually idealized as an infinite source or sink for charge, which can absorb an unlimited amount of current without changing its potential. (wikipedia.org)
  • It was then discovered, probably by the German scientist Carl August Steinheil in 1836-1837, that the ground could be used as the return path to complete the circuit, making the return wire unnecessary. (wikipedia.org)
  • carry
  • In communications and electronic engineering, a transmission line is a specialized cable or other structure designed to carry alternating current of radio frequency, that is, currents with a frequency high enough that their wave nature must be taken into account. (conceptdraw.com)

  • I_{1}R_{G}} , across R G {\displaystyle \scriptstyle R_{G}} occurs and the ground connection of both circuits is no longer at the actual ground potential. (wikipedia.org)
  • It occurs in almost all electronic devices, and results from a variety of effects, though always related to a direct current. (wikipedia.org)
  • Thus
  • A tube may not exhibit the full shot noise effect: the presence of a space charge tends to smooth out the arrival times (and thus reduce the randomness of the current). (wikipedia.org)
  • utility
  • 21 . The equipment of claim 9 , wherein the timer is adapted to coordinate with an electric utility. (google.ca)
  • In New York City, a woman named Jodie S. Lane was electrocuted by a five-foot by eight-foot road utility vault plate energized by an "improperly insulated wire" in January 2004. (wikipedia.org)
  • charge
  • The root-mean-square value of the shot noise current in is given by the Schottky formula i n = 2 I q Δ B {\displaystyle i_{n}={\sqrt {2Iq\Delta B}}} where I is the DC current, q is the charge of an electron, and ΔB is the bandwidth in hertz. (wikipedia.org)
  • Since outdoor antennas are prone build-up of static electric charge, the path for the static to drain to ground through an autotransformer balun can be a distinct advantage. (wikipedia.org)
  • Electrical conductivity is a measure of how well a material transports an electric charge. (wikipedia.org)
  • audio
  • Each shift in offset voltage or current lasts for several milliseconds, and the intervals between pulses tend to be in the audio range (less than 100 Hz), leading to the term popcorn noise for the popping or crackling sounds it produces in audio circuits. (wikipedia.org)
  • earth
  • Electrical circuits may be connected to ground (earth) for several reasons. (wikipedia.org)
  • This is done to prevent harm resulting to the user from coming in contact with any such dangerous voltage in a situation where the user may, at the same time, also come in contact with an object at ground/earth potential. (wikipedia.org)
  • The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices such as cell phones and media players as well as circuits in vehicles may be spoken of as having a "ground" connection without any actual connection to the Earth, despite "common" being a more appropriate term for such a connection.
