nec-essary in such circuits to insert a cer-tain amount of concentrated capacity tobuild up the current. In the radio-frequency circuits of wireless telegraphapparatus, current flows at frequenciesbetween 20,000 and 1,000,000 cycles persecond and if this current is to be trans-ferred by magnetic… … 60 CYCLESA.C Fig. 45—Sliowing How Resonance Is Obtained in Alter-nating Current Circuits. second circuit is then said to be resonant to the impressed frequency and the flow of current isgoverned solely by its resistance. Straight wires possess both capacity and inductance, which are said to be…
