Homework Statement
(image attached)
For the circuit of Fig.30.17 in the textbook, let C = 13.0nF , L = 27.0mH , and R = 80.0Ω .
A). Calculate the oscillation frequency of the circuit once the capacitor has been charged and the switch has been connected to point a
B). How long will it take for the amplitude of the oscillation to decay to 10.0% of its original value?
C). What value of R would result in a critically damped circuit?
Homework Equations
The Attempt at a Solution
I was able to get part A and part C, but I am having a really hard time with B. For A, i got 8490 Hz and for C i got 2880 Ohms. I was able to understand those very well, but I cannot figure out B at all. I have no idea how to relate any of this information to the amplitude.
Any help would be greatly appreciated.
Thanks in advanced.
