T in seconds, R in ohms and C in farads
The plot below was drawn by Turtle Art (the thin black lines were added later. C was 4uF, the load provided by the XO is in the order of 100k ohms. In the two plots, Rx was 100k ohms and open circuit. The calculated resistance of the XO1 is
R = T/C
= 0.32/(4x10^-6) = 80k
and the parallel of 100k and the XO1
R = T/C
= 0.14 /(4x10^-6) = 35k
