It seems that work would be done by the current in the pulse.
joules being the energy measurement.

if the cap it 1uF or 100uF doesn't the amout of work performed
change ?

It seems that by charging a cap directly thru a semiconductor with
low resistance, the time constants would be so low as to not offer
any benefits to one size cap or the other.

I mean that the 100uF will not take 100 times longer to charge, but
will offer signifigantly more energy for work.

or, am I confusing the RC (charge/drain) with a circuit that offers
control over the entire pulse and duty cycle ?

I'm thinking of charge/drain and setting the frequencies based on the
charge voltage.
