**inductance**of 20, 30 and 40 henrys respectively. - If L and N are the
of any two circuits which have a coefficient of mutual**inductances****inductance**M, then M/-/ (LN) is called the coefficient of coupling of the circuits and is generally expressed as a percentage. - It can be shown that if two circuits, both having capacity (C) and
**inductance**(L), are coupled together inductively, then, when oscillations are set up in one circuit, oscillations of two periods are excited in the other differing in frequency from each other and from the natural frequency of the circuit. - In this case a closed condenser circuit is formed with a battery of Leyden jars, an
**inductance**coil and a spark gap, and oscillations are excited in it by discharges created across the spark gap by an induction coil or transformer. - One end of the
**inductance**coil is connected to the earth, and some other point on the closed condenser circuit to an antenna of appropriate length. - In many cases additional condensers or
**inductance**coils are inserted in various places so that the arrangement is somewhat disguised, but by far the larger part of the electric wave wireless telegraphy in 1907 was effected by transmitters having antennae either inductively or directly coupled to a closed condenser circuit containing a spark gap. - Jars or of Leyden panes immersed in oil or some form of air condenser, and the
**inductance**coil or primary circuit of the oscillation transformer consists of a few turns of highly insulated wire wound on a frame and immersed in oil. - The oscillations are controlled either by a key inserted in the primary circuit of the exciting induction coil or transformer, or by a key cutting in and out of the primary condensers or throwing
**inductance**in and out of the closed oscillation circuit. - When electric oscillations are set up in an open or closed electric circuit having capacity and
**inductance**, and left to themselves, they die away in amplitude, either because they dissipate their energy as heat in overcoming the resistance of the circuit, or because they radiate it by imparting wave motion to the surrounding ether. - On the other hand, if a closed oscillation circuit is constructed having capacity and considerable
**inductance**, then oscillations can be set up in it by very small periodic electromotive forces provided these have a frequency exactly agreeing with that of the condenser circuit. - An antenna of suitable capacity and
**inductance**to a nearly closed electric circuit consisting of a condenser of large capacity, a spark gap and an**inductance**of low resistance. - The resonance in the singer's deep voice made the song sound more powerful.
- These mechanical qualities correspond to
**inductance**and capacity in electric circuits. - Over this primary is wound a secondary circuit of five to ten turns which has one end connected to the earth through a variable
**inductance**coil and the other end to an antenna. - His proposed radiator and absorber consisted of two wing-shaped plates of copper, the transmitter plates being interrupted in the centre by a spark gap, and the receiver plates by an
**inductance**coil from the ends of which connexions were made to a coherer. - When the methods for effecting this had been worked out practically it finally led to the inventions of Slaby, Braun and others being united into a system called the Telefunken system, which, as regards the transmitter, consisted in forming a closed oscillation circuit comprising a condenser, spark gap and
**inductance**which at one point was attached either directly or through a condenser to the earth or to an equivalent balancing capacity, and at some other point to a suitably tuned antenna. - The receiving arrangements comprised also an open or antenna circuit connected directly with a closed condenser-
**inductance**circuit, but in place of the spark gap in the transmitter an electrolytic receiver was inserted, having in connexion with it as indicator a voltaic cell and telephone. - Duddell discovered in 1900 that if a continuous current carbon arc had its carbon electrodes connected by a condenser in series with an
**inductance**, then under certain conditions oscillations were excited in this condenser circuit which appeared to be continuous. - 2 In Donitz's wave meter a condenser of variable capacity is associated with
**inductance**coils of various sizes, and the wave meter is placed near the antenna so that its**inductance**coils have induced currents created in them. - From the known value of the capacity in that position and the
**inductance**the frequency can be calculated. - The Fleming closed circuit wave meter, called by him a cymometer, consists of a sliding tube condenser and a long helix of wire forming an
**inductance**; these are connected together and to a copper bar in such a manner that by one movement of a handle the capacity of the tubular condenser is altered in the same proportion as the amount of the spiral**inductance**which is included in the circuit. - An improvement was effected in this respect by the introduction of the " bridging " system, in which the bells possessing high
**inductance**are placed in parallel between the two wires of the circuit. - In one arrangement, now in extensive use, each telephone set is fitted with a relay of high
**inductance**which is bridged across the circuit in series with a condenser. - In circuits possessing high resistance and capacity and low
**inductance**per mile, telephonic currents are rapidly attenuated, and the higher the frequency the more rapid is the attenuation. - 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. - Pupin showed that by placing
**inductance**coils in circuit, at distances apart of less than half the length of the shortest component wave to be transmitted, a non-uniform conductor could be made approximately equal to a uniform conductor. - The introduction of
**inductance**coils into such circuits renders them more susceptible to trouble from atmospheric electricity and more sensitive to leakage variations. - The problem, however, of constructing a deep-sea cable satisfactorily, with suitable
**inductance**coils inserted at short distances apart, is a difficult one, and one which it cannot be said has been solved. - 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 those cases in which the power - absorbing circuit is inductive, the coil of the wattmeter connected across the terminals of the power-absorbing circuit must have an exceedingly small
**inductance**, else a considerable correction may become necessary. - In the 9th series (1834) he announced the discovery of the important property of electric conductors, since called their self-induction or
**inductance**, a discovery in which, however, he was anticipated by Joseph Henry in the United States. - He added definiteness to the idea of the self-induction or
**inductance**of an electric circuit, and gave a mathematical expression for the current flowing out of a Leyden jar during its discharge.
