2. The circuit shown in Figure-2 is at steady state
before the switch closes at time t= 0. The input to the
circuit is the voltage of the voltage source, 12 V. The
output of this circuit is the voltage across the
capacitor, v(t).
a. Determine v(t) for t>0.
b. Use Matlab Simscape Electrical to build and plot
the output, v(t), as a function of t (by using scope). Use
the plot to obtain an analytic representation of v(t) for t
>0.

Figure-2
Hint: We expect v(1) = A + Bet for t > 0, where A, B, and z are
constants to be determined.
Modify the circuit given in this example (build figure-2)

You will obtain a graph as figure 2-b and by using graph and
substituting three 't' values to v(t) then you can find A, B and r.
