1. The problem statement, all variables and given/known data An oscillating LC circuit has a current amplitude of 7.20 mA, a potential amplitude of 250 mV, and a capacitance of 240 nF. (a) What is the period of oscillation? (e) What is the maximum rate at which the inductor gains energy? 2. Relevant equations Possibly: Energy stored in an inductor = 1/2 * L * I^2 i = -wQsin(wt+ø) 3. The attempt at a solution Energy per unit of time is Watts. If I find the equation for energy stored in an inductor, I can differenceate that with respect to time and find its maximum value. I thought that this would be: dE/dt = P = -L(w^3)(Q^2)sin(wt)cos(wt) And isn't the maximum value for this just (1/2)L(w^3)(Q^2) ? And isn't that just 0.9 mW ? I've done this problem wrong several times so far, so is this one right?
