Abstract :
At a meeting of the Institute of Radio engineers to be held in the Engineering Societies Building, New York City, on April 5 at 8:15 p. m., a paper on the “Resistance and Capacity of Coils at Radio Frequencies,” by Professor John H. Morecroft of Columbia University, will be presented. The paper describes theoretically and experimentally the behavior of numerous types of inductances at radio frequencies and contains important design data.
