Item 3 Calculate tie oscillauon frequency of Ine CINCUIL f = 2140 Hz A 23.0 /F capacitor is charged by a 140.0-V power supply, then disconnected from the power and connected in series with a 0.240- Submit Previous Answers mH inductor. Correct Part B Calculate the energy stored in the capacitor at time t= 0ms (the moment of connection with the inductor). U = 0.225 J Submit Previous Answers Correct Part C Calculate the energy stored in the inductor at t = 1.40 ms . IVO AEd U = 1.42 . 10 -4" energy stored in capaciton = energy stored in induction at $=0ms at J= ums, werent will be maximum 2 2 L CV = LX L X Imax 2 / from ( b) - 2 (V= 0:275J 0.225 J = 1 X 0. 240410 4 Imax 2 Imade = 2 0-225 x 103 0- 240 Imax = 43-30 A Now, I = Imanl s'in wit W = 2 TT f at J = 140m8 W = 2+3-14 x 2140 HZ 7 = 1- 40* 10'8 - W = 13, 439-2 grad 18 I = 43.30 8in / 13 439- 2 9PU / 8 X 1-40 X 10'9 ) I = 43.30 sin ( 18- 81488 ) = 1- 50116 A Now, energy stored at J= 1.40 m/s E = _ LIZ 2 = 1 X 0-24 x 10 4 (1- 50116 ) 2 E = 27X10 - 4 J Ans
