8.23 why ic(0+)=45mA not 50mA? 8.21 Assume the underdamped voltage response of the ocircuit in Fig. 8.1 is written as mit wv(t)= (A1 +A2)e cos wt +j(A - A2)e a sin wt en in moves -at -at 0. The initial value of the inductor current is Io, and the initial value of the capacitor voltage is Vo- Show that A2 is the conjugate of A1. (Hint: Use the same process as and A2.) outlined in the chapter to find A...
