In over three decades in the business I have never seen a circle with an X in it used for a light bulb.

Mark,

This symbol for a lamp was and is still commonly used in the UK.

It's European notation (the X), in my country (France) we use also this symbol.

@Harti
Thanks for the schemtic I undertsand it better: first it charge in the first quadrant via the load then it discharge always via the load in the second quadrant same things but it reverse for the third and fourth quadrant...
Eric Dollard Four Quadrant theory ?
Energy from Sqrt(-1) ?
So the energy stored in cap and the other dissipated in R must be equal or superior in the cap...
Putting in series for the discharge, help to discharge fast by reversing the curent back to source...
Then, I guess that the green curve is I.
Thanks.
