Question
A capacitor C = 6 micro Farads is connected in series with an inductor L = 135 mH and a battery V = 12 volts at t < 0 . At t = 0, the battery is disconnected.a) How many seconds will it take for the energy of the inductor to be 1/2 the energy of the capacitor before one period has elapsed ? A capacitor C = 6 micro Farads is connected in series with an inductor L = 135 mH and a battery V = 12 volts at t < 0 . At t = 0, the battery is disconnected.
a) How many seconds will it take for the energy of the inductor to be 1/2 the energy of the capacitor before one period has elapsed ?
Explanation / Answer
1/2 LI^2 = 1/2 CV^2
LI^2 = CV^2
and we know w=[ 1/LC ]^1/2 from this we get the value of the time
