The A B C of vacuum tubes in radio reception; an elementary and practical book on the theory and operation of vacuum tubes as detectors and amplifiers. Explains non-mathematically the fundamental principles upon which all vacuum tube circuits are based. Includes practical circuits and practical questions and answers. It is written especially for the beginner. All electrical and radio terms are fully explained (1922)

on-stant amplitudes. If an E. M. F. has constantly decreasing amplitude it willproduce a current of constantly decreasing amplitude. Also,if the amplitudes of the E. M. F. decrease rather rapidly,the current will cease to flow after a short period of timebecause of the absence of E. M.
