Current Question (ID: 20557)

Question:
$\text{In an LC oscillating circuit with } L = 75 \text{ mH and } C = 30 \mu F. \text{ The maximum charge of capacitor is } 2.7 \times 10^{-4} C. \text{ Maximum current through the circuit will be:}$
Options:
  • 1. $0.18 \text{ Amp}$
  • 2. $0.24 \text{ Amp}$
  • 3. $0.72 \text{ Amp}$
  • 4. $0.92 \text{ Amp}$
Solution:
$\text{total energy} = \frac{q_{\text{max}}^2}{2C} = \frac{1}{2} L i_{\text{max}}^2$ $i_{\text{max}} = \frac{q_{\text{max}}}{\sqrt{\frac{L}{C}}} = \frac{2.7 \times 10^{-4}}{\sqrt{\frac{75 \times 10^{-3}}{30 \times 10^{-6}}}} = 0.18 \text{ Amp}$
