Question
Consider the circuit of Figure P9.52 in which R1 = 4Ohm, R2 = 4Ohm, L = 5/12H, C = 25 mF. Find the roots of the characteristic equation. CHECK: -8, -12 If Vin(t) = -20u(-t) V, find vC(0-), vC(0+), iL(0-), iL(0+), and vC(t) for t>0. Hint: After finding the initial voltages and currents, draw the equivalent circuit valid for t > 0. Check your answer for vC(t) using the "dsolve" command in MATLAB. Plot vC(t) for 0 t 2 sec using MATLAB or the equivalen. Be sure you properly label your plot. If vin(t) = -20u(-t) + 20u(t) V, find vC(t) for t> 0. If vin(t) = -20u(-t) + 20u(t) -20u(t-1)V, find and plot vC(t) for 0 t 2sec.Explanation / Answer
it's always better to solve a problem of matlab on matlab itself rather than on paper. its comfortable to use various tools. try it on matlab by putting the charecteristcs equation on it. hope it helps
