# RLC circuit

Posted on 2009-05-12

The instructions are the following.

Connect a function generator (squarewave!!),

large inductor and small capacitor in series, with the cap. grounded.

Watch cap. voltage on o'scope-> exponentially-decaying sinewave.

Measure half life (thl) to find time constant (tau=thl/ln2). Measure

oscillation period (Td) to find damped resonant frequency (Wd) Ask

question: Does 1/tau^2 + w(omega)d^2=1/(LC)??

Is there some way to get the half life time and oscillation period of this circuit if

I know the values of the RLC? I need to compare the experiments with some real

results just to make sure I did this correctly? Also the R here is from the function generator
