circuit will have certain natural period of
vibration, that say that when the elec

electrical electro-magnetic vibration a
20 certain period takes place, and this de
pends upon the capacity and self induction,
such period may varied approximately
accord with the period the engine.

In case the power the engine coin-

to control the period, and clear that if
