Not illustrated. 1910 Excerpt: ... resultant main current when both are connected in parallel. It will be seen that the condenser current shows slight irregularities, as a capacity or spring responds very readily to irregularities in the applied P.D. or force, while inductance or inertia tends to smooth them out. When placed in parallel, therefore, the inductance and capacity can only compensate for one another as far as the principal current wave is concerned, and the mains supply the irregularities, as shown. With a perfectly sinusoidal P.D. the resultant current at the right frequency would be practically nil. This property of condensers and choking coils to mutually supply current to each other, or to compensate for one another, is often of great value in practice. As a rule an alternate-current supply system is considerably inductive owing to the number of transformers, motors, and arc lamps in circuit, all of which act more or less like choking coils. This, of course, means that the main current will lag behind the E.M.F. of the generators; and, as will be seen later, this tends to bad regulation of the voltage of the circuit. Fig. 97.--Composition of currents But, as we know, long cables m Paralle1' act as condensers, and consequently tend to compensate for this inductance, and further, as we shall also see later, synchronous motors can be made to act like condensers, and are often so used to correct the inductive effect of other machinery. It is possible yet that with improved manufacture of condensers they may be used extensively on alternate-current supply systems. Calculation of Parallel Circuits in General--The formula obtained for capacity, resistance, and inductance in parallel, though interesting, is not sufficiently general, as practical circuits do not as a rule fulfil the ...
