You are NOT allowed to solve the circuit with phasors, all calculations must be done in the time domain. If switch S₁ is initially closed and circuit reaches steady state and is opened at t = 0 seconds, answer the following questions. Questions (b) and (c) the switch S₁ is closed and for questions (d) to (f) the switch S₁ is opened. Redraw the circuit and clearly label all voltages and currents for each component. b) calculate the voltage over the capacitor C1 at t = 0-seconds. c) calculate the current flowing through inductor L1 at t = 0- seconds. d) calculate the natural frequency w0 and damping factor a for t > 0 seconds. e) calculate the roots (factors) of the characteristic equation. State if the circuit is underdamped, overdamped or undamped. f) calculate the current flowing through inductor L1…
