Question

10. -/10 points My Notes Ask Your Teacher The switch in the figure below is connected to position a for a long time interval. At t = 0, the switch is thrown to position b. After this time, what are the following? (Let C = 1.20 uF.) 0.100 H 12.0 V Ic (a) the frequency of oscillation of the LC circuit Hz (b) the maximum charge that appears on the capacitor CNC (c) the maximum current in the inductor CamA (d) the total energy the circuit possesses at t = 3.00 s Need Help?

Answer 1

→ Solution! First: eiscuit for tnitial Condition ( means before t-o) ROV - I 1 C= liQOME becoz switch das Connected Connected for As long time, long time before t=0, It means Capacity will be in fully charged state before t=0 (behaves like an oben circuit element → "modified 1012 Circuiti + Q0V *p.CO) = loovalt! Circuit after t= 0.70 M L Co)-kont - - - - DONE here there is no sauce available with the chcuit In second Situation therefore we can conclude that the maximum voltage that can be appear across the capacites will be may = V(o)=120 @ frequency of, oscillation is given by ! 8x = an Ice HZ] - 27 JoelX los cynor > Hy = 0.45968203 er X1-2011" => Th= 459•6HZ 1 Ans
