[simpits-tech] RC Timer delay

[Stig Joergensen]

Ross... please explain why....

As I see it, the resistance over the capisitator is pratical zero
(remeber we are talking of DC not high frequency, where things start to
shift :-) compared to the R1 value, And by applying the normal u=r*i
rule; out should be aprox the strobe as long as it is held high....
