o an alternating current is called impedance. It can beshown that the impedance of a circuit is equal to ^/R^ + ^irVU, whereR is the resistance, L is fhe inductance of the circuit, and n is the fre-quency of the alternating current. The proof of this is given in treatiseson alternating currents.… … Fig. 468. The frequency of a Leyden jar discharge is ordinarily very high (§ 713).and so a discharge has a large impedance even through a single loop. Thusin Fig. 469 the discharge will leap across a considerable air-gap P, soonerthan go through the loop L. 698. The Oscillograph. An ordinary…
