In an oscillating series rlccircuit, with a 6.13 ω resistor and a 15.2 h inductor, find the time required for the maximum energy present in the capacitor during an oscillation to fall to half of its initial value.

time for maximum energy is 1.718 sec

Explanation:

Maximum energy on the capacitor is given as  

Maximum energy

The maximum charge is given by

                       Or

                    Or

solving for t

Putting all value to get desired value

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
