The energy in the capacitor at the instant after the switch is closed, based on the potential across the capacitor is 31 mJ
<h3>What is the energy amount in the capacitor?</h3>
Because total energy is constant, this can be found by the formula:
= Initial energy in capacitor - Energy in inductor
The initial energy in the capacitor is:
= 0.5 x 4 x 10⁻⁶ x 200²
= 0.08J
The energy in the inductor is:
= 0.5 x 0.2 x 0.7²
= 0.049
The energy in the capacitor at that instant is:
= 0.08 - 0.049
=0.031 j
= 31 J
