Answer:
19.5 mJ
Explanation:
Assuming perfect components without resistance or losses, the circuit should oscillate indefinetly.
The circuit will have a natural pulsation of
So, by the time t = 2.4 ms, 333.33 cycles would have passed
Therefore it would be at one third after the beginning of the cycle. The circuit would be in an equivalent state as t = (7.2 us)/3 = 2.4us
At t=0 the capacitor is fully charged, so the voltage is maximum and the current is 0. The current will increase towards a maximum of 800 mA at t=T/4, then decreas to 0 at t=T/2, decrease to -800 mA at 3T/4 and go back to 0 at t=T following a sine wave.
The equation of this sine wave would be
Since w = 2π/T
w * T = 2π
The current stored in an inductor is
