Homework Help: Charging and dischaging capacitors

  1. Feb 11, 2010 #1
    1. First you fully charge a capacitor (C = 6.4 µF) with a 12V battery. Then you disconnect the battery and discharge the capacitor through a resistor (R = 3 Ohms) and an inductor (L = 2.0 x 10-3 H) in series.

    2. What is the charge on the capacitor when you begin discharging at t= 0?

    How long does it take for the charge amplitude to fall to one tenth of initial value?

    At what time does the charge first fall to one tenth of its initial value?



    3. The attempt at a solution
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    Well what have you thought about doing? What dictates how fast a capacitor in an RLC (Resistor - Inductor - Capacitor) circuit will lose charge?
