The source-free circuit depricted in Fig. 9.1 is constructed using a 10mH inductor, a 1mF capacitor, and a 1.5k ohms resistor.
a) Calculate alpha ( neperfrequency or exponential damping coefficient), omega-sub-delta (natural resonance frequency), and omega-sub-zero (resonant frequency).
b) Write the equation which describes the current i for t>0.
c) Determine the maximum value for i, and the time at which it occurs, if the inductor initially stores no energy and v(0-)=9V
