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 = 425 Ω. The values for the inductances are: L1-398 mH and L2-108 mH. The capacitance is C-186 μF and the battery voltage is V- 12V. The positive terminal of the battery is indicated with a +sign nes ir a 000 レ L2 ) The switch has been closed for a long time when at timet-o0, the switch is opened. What is UL1(O) the magnitude of the energy stored in inductor Lijust after the switch is opened? Submit 2) What is ulo, the resonant frequency of the circuit just after the switch is opened? radians/s Submit 3) What is Omax, the magnitude of the maximum charge on the capacitor after the switch is opened? HC Submit 4) What is Qlt), the charge on the capacitor at time t t-4.17 ms Qtt1) is defined to be positive ifV(a) V(b) is positive. HC 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 timet t2? Submit
