atter does not rise high enough to cross the gap so that the con-denser soon begins to return energy to the charging circuit. It doesthis until its potential and the charging potential (and current if theyare in phase) falls to zero. It then begins to absorb energy again with thereverse potential,… … Fig. 36. done on the condenser during the first half of an alternation; the zig-zag line indicates the number and amplitude of vibrations made bythe closed circuit in transferring the energy to the radiating circuit.The area included by the curve on the right of the zig-zag line repre-sents the…
