Figure 35. Rc less than RL.
c. Charging waveform when Rc is greater than Rch. Figure 36 shows the
dampened square wave pattern that appears across a PFN that has a
characteristic resistance greater than the source resistance.
If you see
this pattern on the scope it means one of these two things: the
characteristic resistance of the PFN has increased; or, the source
resistance has decreased.

Rc greater than Rch.
d. Discharging waveform when Rc is greater than RL.
Figure 37 shows
the dampened square wave across a load that has less resistance than the
characteristic resistance of the PFN. This pattern on a scope means one of
two things: the characteristic resistance of the PFN has increased; or, the
load resistance has decreased.
