In the question whay v(0)=0 v?! 8.14 The switch in Fig. 8.69 moves from position A to position B at t = 0 (please note that the switch must connect to point B before it breaks the connection at A, a make-before-break switch). Find v(t) for t> 0. 30 2 4 H ww ele B9 20 V 0.25 F (1) 102 Figure 8.69 For Prob. 8,14. Chapter 8, Solution 14. When the switch is in position A, v(0)=0 and i(0) = 20 = 0.5A. When the switch is in 40 position B, we have a source-free series RCL circuit. R 10 =1.25 2x4 %3D 2L 1 3D1 %3D VLC x4 Since a > w,, we have overdamped case. S12 = -a t Ja - w = -1.25t 1.5625-1= -0.5 and -2 v(t) = Ae 2+ Be0.5t (1) v(0) = 0 = A + B (2) i(0) = c dv(0) = 0.5 dt dv(0) 0.5 dt dv(t) = -2Ae-2t -0.5Be-0.5t dt But dv(0) =-2A - 0.5B = 2 dt (3) Solving (2) and (3) gives A=-1.3333 and B = 1.3333 v(t) =-1.3333e 4 + 1.3333e 0.5t V.
