Facets:
value: as the resistance
type: MANNER
value: from the power
type: OTHER
Source sentences:
text: Then the radiation resistance is calculated from the power by conservation of energy, as the resistance the antenna must present to the input current to absorb the radiated power from the transmitter, using Joule's law R R = P R
