Growth Factors for Analysing Exponential Data - This page is in the process of development


Video Tutorials - Applications in science

  • Radioactivity decay - Half life:-  At = A0exp(-0.693 t / T1/2)
  • Bacterial colony decay - Decimal reduction time:-  Nt = N0exp(-2.303 t / TD)
  • Baterial growth - Generation time:-  Nt = N0exp(+0.693 t / TG)
  • Capacitor discharge - Decay time:-  Vt  = V0exp(- t / τ)
