Coulomb - in Everyday Terms

In Everyday Terms

  • The charges in static electricity from rubbing materials together are typically a few microcoulombs.
  • The amount of charge that travels through a lightning bolt is typically around 15 C, although large bolts can be up to 350 C.
  • The amount of charge that travels through a typical alkaline AA battery is about 5 kC = 5000 C ≈ 1.4 Ah. After that charge has flowed, the battery must be discarded or recharged.
  • According to Coulomb's Law, two point charges of +1 C, placed one meter apart, would experience a repulsive force of 9×109 N, a force roughly equal to the weight of 920,000 metric tons of mass on the surface of the Earth.

Famous quotes containing the words everyday and/or terms:

    “Nature’s law says that the strong must prevent the weak from living, but only in a newspaper article or textbook can this be packaged into a comprehensible thought. In the soup of everyday life, in the mixture of minutia from which human relations are woven, it is not a law. It is a logical incongruity when both strong and weak fall victim to their mutual relations, unconsciously subservient to some unknown guiding power that stands outside of life, irrelevant to man.”
    —Anton Pavlovich Chekhov (1860–1904)

    “Theology—An effort to explain the unknowable by putting it into terms of the not worth knowing.”
    —H.L. (Henry Lewis)
