radiant power, \(P\)

https://doi.org/10.1351/goldbook.R05046
@P04792@ emitted, transferred or received as radiation. SI unit is \(\text{J s}^{-1} = \text{W}\).
Notes:
  1. Mathematical definition: \(P = \text{d}Q/\text{d}t\). If the @R05039@ \(Q\) is constant over the time interval, \(P = Q/t\).
  2. In @R05115@, flux  (\(\varPhi\)) is used with the same units as \(P\). The symbol \(\varPhi\) is reserved for @Q04991@ in @P04588@. Therefore, the use of flux (\(\varPhi\)) is not recommended.
