Solve this. find the initial conditions ic(0-) and vc(0-) the switch opens at t=0 so it's closed at t=0- dont copy the response from previous because it's wrong. please solve in great detail explaining everything step by step. now the way i thought about it is Getting millman voltage (1/3)-2 / (1/3)+(1/2) and it's the same as Vc as both are nodal voltages but i wasn't sure if correct. because i didnt take into consideration all voltages (Vc here) even though it's the same so i'm quite confused. please explain to me if i'm correct and if not tell me why and where my thinking was flawed. thank you
3. Consider the RL circuit with a constant voltage source shown in the diagram below. The
values of the resistor, inductor, and input voltage are R = 100, L = 100 mH, and Vo = 12V,
respectively.

When the switch closes at time t = 0, the current begins to flow as a function of time. It
follows from Kirchoff's voltage law that the current is described by the differential equation

4. Consider the RL circuit with a sinusoid voltage source shown in the diagram below. The values
of the resistor, inductor, input voltage amplitude and frequency are R = 5, L = 50mH,
and Vo = 10 V, respectively. The input voltage frequency w is variable. Assume that the
circuit has reached steady state.

The input voltage can be described using the complex sinusoid function
V(t) = Voejwt
The current is given by a sinusoid with same the frequency was the input voltage, but a
different magnitude and different phase. The physical voltage and current are obtained by
taking the real part. In complex form, the current is given by

The differential equation that describes the current follows from Kirchoff's voltage law, and
