In series L-C-R circuit C=2 F , L=1 mH and R=10 . What is the ratio of energies stored in the inductor and the capacitor, when the maximum current flows in the circuit?

Step-by-step solution

At maximum current condition, system is at resonance condition. X_C=X_L U_C U_L = 1 2 C V^2 1 2 L i^2 = C i^2 R^2 L i^2 U_C U_L = 2 10⁻⁶ 10⁻³ 100 Hence, we get U_C U_L = 2 10 = 1 5
