    Expected in 10 s
    1.0 MW
    0.10 mF
    The next comment refers to the speed here.
    20 flashes in 10 seconds
    2.2 MW
    0.10 mF
    twice the resistance gives half the rate as the one just done.
    10 Flashes in 10 seconds
    4.7 MW
    0.10 mF
    doubled resistance = half speed of fill/drain rate!
    5 Flashes in 10 seconds
    10.0 MW
    0.10 mF
    Half the rate of flashing again.
    2 Flashes in 10 seconds
    10.0 MW
    0.01 mF
    The cap is 1/10 the size.  That effects how quickly it drains!
    10 Flashes in 10 seconds
    4.7 MW
    0.01 mF
    This actually is ten times faster fill/drain rate as the .1 uF.
    50 Flashes in 10 seconds
    2.2 MW
    0.01 mF
    The pattern continues.  Yes, you can count it. 10/second.
    100 Flashes in 10 seconds
    1.0 MW
    0.01 mF
    This is twice as fast as the one just completed.  You can see that it is flashing, but you can't count it.  It's going at 20/sec.
    200 Flashes in 10 seconds
