Resonance, Bandwidth & Q Factor

In series LCR circuit C = 2 uF, L=1 mH and R= 10 $\Omega$ . What is the ratio of energies stored in the capacitor and inductor when maximum current flows through circuit?

Show answer and solution

Answer: (c)

At maximum current $\frac{dI}{dt} = 0$ , so $V_C = IR$ .
$\frac{U_C}{U_L} = \frac{\frac{1}{2}CI^2R^2}{\frac{1}{2}LI^2} = \frac{CR^2}{L}$
$\frac{U_C}{U_L} = \frac{2\times10^{-6}\times100}{10^{-3}} = 0.2$
So the answer is (c) $0.2 : 1$ .
