Question

A circuit is constructed with a resistor, two inductors, one capacitor, one battery and a switch as shown. The value of the resistance is R1 4252. The values for the inductances are: L 1 398 mH and L2-108 mH . The capactance C-186 μF and the battery voltage is V-12V. The positive terminal of the battery is indicated with a sign 1) The switch has been closed for a long time when at time 0, the switch is opened. What is ULI(0), the magnitude of the energy stored in inductor L1 just after the switch is opened? J Submit 2) What is wo the resonant frequency of the circuit just after the switch is opened? radians/s Submit 3) What is Qmax, the magnitude of the maximum charge on the capacitor after the switch is opened? C Submit 4) What is Ott), the charge on the capacitor at timet t-4.17ms. Q(ty) is defined to be positive if V(a)-Vb) is positive C Submit 5) What is t2, the first time after the switch is opened that the energy stored in the capacitor is a maximum? ms Submit 6) What is the total energy stored in the inductors plus the capacitor at time t-t? J Submit
