An illustration from Principles and practice of electrical engineering, 1914, leaf 244
e capacity becomes equal to kF farads whenanother dielectric is used. The constant k is called the specificinductive capacity of the material. Average values of k aregiven in the following table for the materials generally usedin commercial condensers.

If a constant e.m.f. is applied across the terminals of the circuitshown in Fig. 243, then a momentary current will flow in the direc-tion shown in diagram A to charge the condenser but currentwill not flow continuously since the circuit is…
