Of course, I remember that now. In Her Royal Kingdom you
would experience this only 100 times per second. Yes, Yes.
The MA meter is only showing an average of the load every
second. 60hz=on/off 120 x per second.
50hz=on/off 100 x per second. I dont supose there is a way
to time the fuse differantly? Though it is easier to see the differance
between 450ma and 500ma than it is to see that of 27 and 30ma.
How about a fuse made similar to an electrode. Where as the
emmision coating would act as the trigger. Is the range of 27-30ma
still so small. In other words the fuse could be a small luminous tube,
the trigger of this fuse would be the instable chemical reaction of
the emmission coating at 30ma. While at 24- 27ma the
emmission coating might be quite stable.
To bodly go where no man has gone before...
Peace.
