Physics

I worked out the fields radiated by an electric dipole in class,and they are also in 11.1.2 of the text. These fields carry energyaway and we know the radiated power. From the point of view of thesource of the time dependent current (and charge) in the dipole,the antenna could just as well be a resistance with resistance R.Find the value of this resistance, known as the “radiationresistance.”
