لمس R = 400 ε = 12V 2μF 1mH1uF: a) In the circuit, both capacitors are initially uncharged. The itch S is closed at t = 0. Calculate iR, iL at t = 0. b) When the current in the circuit reached steady state, calculate the energy stored in the 2uF capacitor and in the inductor. c) After the current reached steady state, S is opened and time is reset to t = 0. Calculate the maximum charge the 2μF capacitor can get.
