the filament of an incandescent lamp has a 150 Ohms resistance and carriesa direct current of 1.00 A. The filament is 8.00 m long and 0.900 mm in radius. a) Calculate the Poynting vector at the surface of the filament associated with the static electric field prodcing the current and the current 's static magnetic field. b) Find the magnitudes of the static electric and magnetic fields at the surface of the filament?
