About
Pedersen became a professor of telegraphy, telephony and radio in 1912.
He became principal of the College of Advanced Technology (Den Polytekniske Læreanstalt) in 1922, a title he held until his death. He was a Fellow of the American Institute of Electrical Engineers and was a member of the British Institution of Electrical Engineers. In 1915 he became a Fellow of the Institute of Radio Engineers.
The first expression for the Pedersen current was formulated by Pedersen from in his 1927 work "The Propagation of Radio Waves along the Surface of the Earth and in the Atmosphere", where he pointed out that the geomagnetic field means that the conductivity of the ionosphere is anisotropic.
