Definition of time constant in English: time constantnoun Physics A time which represents the speed with which a particular system can respond to change, typically equal to the time taken for a specified parameter to vary by a factor of 1−1/e (approximately 0.6321). Example sentencesExamples - The hyperinflation may be explained completely by the time constant of the respiratory system exceeding the time available for tidal exhalation.
- One way is to vary the time constant of the slow negative-feedback variable.
- The time constant of the signal-recovery process yields information on potential heart damage.
- This time constant, like that for the half-life of a radionuclide, doesn't tell you an age necessarily - assumptions must be applied first.
- This time constant reflects, rather, the lifetime of the first excited singlet state of the complex, which decays rapidly owing to intersystem crossing.
