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 = 134 Q. The values for the inductances are: L1 = 361 mH and L2 = 116 mH. The capacitance is C = 122 uF and the battery voltage is V = 12 V. The positive terminal of the battery is indicated with a + sign. 0000 1) The switch has been closed for a long time when at time t = 0, the switch is opened. What is UL1(O), the magnitude of the energy stored in inductor Ly just after the switch is opened? 0.00145 J Submit You currently have 1 submissions for this question. Only 5 submission are allowed.
