How much power does the sphere radiate
WebThe total power radiated by a blackbody is given by the Stefan-Boltzmann equation, but it is often interesting to know the fraction of power which is emitted in the visible or some other wavelength range. Temperature T = K = °C. Area A = cm 2 = x10^ m 2. Emissivity = (e = 1 for ideal radiator) The total power radiated is P = watts = x10^ watts. WebHow much power does the sphere radiate?

http://electron6.phys.utk.edu/PhysicsProblems/Mechanics/9-Gereral%20Physics/radiation.html Effective radiated power and effective isotropic radiated power both measure the power density a radio transmitter and antenna (or other source of electromagnetic waves) radiates in a specific direction: in the direction of maximum signal strength (the "main lobe") of its radiation pattern. This apparent power is dependent on two factors: the total power output and the radiation pattern of the antenna – how much of that power is radiated in the desired direction. The latter factor is …
