For the circuit shown in figure 4 the switch has been closed

For the circuit shown in figure 4 the switch has been closed for a very long time and then the switch is opened at time t = 0. what is i_1 (0-) the current in the inductor at time t = 0? 72 A 1.0 A 0.5 A 2.0 A None of the above what is u_c(0-). The voltage on the capacitor at time t = 0\"? 4 V 6 V 9 V 12 V None of the above what is t the Laplace-domain current I_2? What is I_2(0+). The current through the capacitor at time t = 0^4? -2 A 0 A 3 A -1 A Nom- of the above
