Definitions

Electronics

  • A value obtained by squaring multiple instantaneous measurements, averaging these over a given time interval, and taking the square root of this average.
  • For a periodic quantity, a value obtained by squaring multiple instantaneous measurements, averaging these over the time of a complete cycle, and taking the square root of this average. In the specific case of sinusoidal AC, the effective current value is equal to 0.707 of the peak value of the current.
