The value of inductance is 25 H and the capacitance is 10 F . The switching frequency is 100 kHz and the duty ratio is 0.5. Which of the above circuit(s) result in valid steady-state operation? Justify your answers. Problem 2: (25 points) Referring to the figure below, plot the following waveforms for 0 &lt; t &lt; 10 s, clearly showing all the relevant magnitudes. Assume that the circuit is in steady state.
