Ehild,
I checked, but we are not given a definition as such of underdamped. But intuitively, afaik, it means a system where the impulse response oscillates rather than moving monotonically. Actually now I am not sure.
I have been thinking about it for a while and came up with the following reasoning:
If all the poles of the transfer function (in s-domain) are in the L.H.P. (left half plane, real part < 0), then the system is not underdamped. So what remains is to show it for a general RC circuit. Any...

Question: Is a general RC circuit, with any topology of interconnected R and C elements, never underdamped?
This is a bonus question in one of my homeworks. The answers to the earlier questions in the problem indeed show that two example RC circuits are not underdamped.
I...
