- If the two circuits are in tune so that the numerical product of capacity and inductance of each circuit is the same or C L, = C L +CL and if k is the coefficient of coupling then the natural frequency of each circuit is n = I /2w / (CL), and when coupled two oscillations are set up in the secondary circuit having
**frequencies**n and n2 such that n = n0/ (i - k) and n = nh,/ (I +k). - In another party line system a harmonic principle is employed: the ringing machines deliver alternating currents of four
**frequencies**, while each bell is constructed to operate at a particular frequency only. - Oliver Heaviside showed mathematically that uniformly-distributed inductance in a telephone line would diminish both attenuation and distortion, and that if the inductance were great enough and the insulation resistance not too high the circuit would be distortionless, while currents of all
**frequencies**would be equally attenuated. - It is also necessary to notice that shunt instruments cannot be used for high
**frequencies**, as then the relative inductance of the shunt and wire becomes important and affects the ratio in which the current is divided, whereas for low frequency currents the inductance is unimportant. - In many experiments, however, different inductions and
**frequencies**are employed, and the hysteresis-loss is often expressed as ergs per cubic centimetre per cycle and sometimes as horse-power per ton.
