Statement of a problem № 41926


Suppose a 50-kW radio station emits EM waves uniformly in all directions (a) How much energy per second crosses a 1.0-m2 area 100 m from the transmitting antenna? (b) What is the rms magnitude of the E field at this point, assuming the station is operating at full power? (c) What is the voltage induced in a 1.0-m-long vertical car antenna at this distance.
