0.
a) At what time t
will the amplitude of the charge oscillations in the circuit be 50%
of its initial value? (Note that we do not know that initial
value.)

In an LRC series circuit, the inductance is 244 mH, the
resistance is 29 Ω, and the capacitance is 354 μF. If the
AC voltage applied across the circuit is given by
V(t) = (12 V)sin(11πt)
calculate the voltage across each element at a time of
t = 0.04 s.
