Page 130 - ... resistance of the rest of the system, T is the interval between the beginning of a discharge and the beginning of the next discharge, and T is the duration of contact for each discharge. We thus obtain for the corrected value of C in electromagnetic measure rC (10) \-e -2IV. Comparison of the Electrostatic Capacity of a. Condenser with the Electromagnetic Capacity of Self-induction of a Coil.
Page 386 - Never did I feel such a tumultuous sensation before,' said the Professor, ' as when all alone in the still room I heard the needles click, and as I spelled the words I felt all the magnitude of the invention, now proved to be practical beyond cavil or dispute.
