This is an interesting technique.  For something like opamps, is there an
optimum series resistor(s) value?  Does that vary from opamp type to opamp type?
 My guess is yes and it has to do with how much current the opamp can supply and
how much the designed load will to draw at maximum.  Are there applications
where one ought not do this?
