Question
*** "u" means micro ***A 28.0 uF capacitor is charged to 160 uC and then connected across the ends of a 4.60 mH inductor.
b) At the instant the current in the inductor is maximal, how much charge is on the capacitor plates?
c) Find the maximum potential across the capacitor.
d) At the instant the potential across the capacitor is maximum, what is the current in the inductor?
e) Find the maximum energy stored in the inductor.
f) At the instant the energy stored in the inductor is maximum, what is the current in the circuit?
Explanation / Answer
b) 0 c) V = C/q = 0.175 V d) 0 e) 1/2CV2 = 4.3*10^-7 J f) 1/2Li2 - 4.3*10^-7 => i = 0.014 A
