    The advantages of multi-phase over single-phase spark transmitters are given; some of which are higher tone, lower condenser voltages, greater reliability (because of spare phases in case of breakdown of one phase), and smaller current broken at key. A 3-phase, 120-cycle, 3-kilowatt set is then described in detail. View full abstract»

    Considering that electrostatic energy is actually in the space surrounding a charged body, the latter is called a "terminal surface." It is shown that capacity is predominantly a function of the maximum lineal dimension of the terminal surface. The volumetric and lineal energy densities in the field are defined and studied in a number of cases. It is proven that the capacity between two terminal surfaces is greatly affected by changing the lineal dimensions of the smaller terminal surface, but not so for changes of the larger. Certain current errors in connection with "mutual capacity" are considered. The practical applications to a radio antenna and to aeroplane counterpoises are given. When a charge traverses a sphere, entering parallel to a diameter, the sphere behaves as a conductor of uniform lineal capacity. Applications of the theoretical considerations are also given in connection with the conductivity of concentrated and dilute electrolytes. View full abstract»

  • The Impedances, Angular Velocities and Frequencies of Oscillating-Current Circuits

    Corresponding to the usual angular velocity (2 Π times the frequency) of an alternating current is the generalized angular velocity of an oscillating current. The generalized velocity is a complex quantity; the real portion determining the damping constant, the imaginary portion the frequency of the current. The author shows that the oscillation impedances of resistances, inductances and capacities are formed in the same way from generalized angular velocities as from the usual angular velocity. The oscillation impedance of any circuit or system of circuits is found by the usual law of resistances for continuous currents, due regard being paid to the rules of complex quantities. It is then shown that free oscillations of any system of circuits select such angular velocities as to reduce the total oscillation impedance to zero. A number of cases of parallel and series oscillating circuits are treated by this method with much simplicity. The total oscillation admittance at a knot point is shown to be zero, as also is the sum of the instantaneous oscillation-impedance drops around a closed loop. The instantaneous discharge power in any oscillation impedance is readily derived and shown to be zero in a pure oscillation system. The problem of coupled circuits is given a preliminary treatment by these methods. View full abstract»
