5) Let vc(t) across the capacitor; R the resistance; C the capacitance, and V(t) the voltage supplied by the voltage source. See the figure below. dvc We get RC +vc = Vt) dt R 20 4v F Suppose the voltage source, V(t) = 4 and the Initial voltage across the capacitor vc(0) = 6 With quantities R = 2 and C = 1 we get the Initial value problem. dvc 2 +Vc =4 dt Vc(0) = 6 (Note: These numbers are probably unrealistic. However; we want to get the idea of how to solve these types of problems) Find the vo

IMI The circuit in the figure is described by the equation
$$
\left[\begin{array}{c}{i_{L}^{\prime}} \\ {v_{c}^{\prime}}\end{array}\right]=\left[\begin{array}{cc}{0} & {1 / L} \\ {-1 / C} & {-1 /(R C)}\end{array}\right]\left[\begin{array}{c}{i_{L}} \\ {v_{c}}\end{array}\right]
$$
where $i_{L}$ is the current through the inductor $L$ and $v_{C}$ is the voltage drop across the capacitor $C .$ Find formulas for $i_{L}$ and $v_{C}$ when $R=.5$ ohm, $C=2.5$ farads, $L=.5$ henry,
the initial current is 0 amp, and the initial voltage is 12 volts.
