MHT CET · Physics · Capacitance
A \(4 \mu \mathrm{~F}\) capacitor is charged to 10 V . The battery is then disconnected and a pure 10 mH coil is connected across the capacitor so that LC oscillations are set up. The maximum current in the coil is
- A 0.2 A
- B 0.1 A
- C 0.4 A
- D 0.25 A
Answer & Solution
Correct Answer
(A) 0.2 A
Step-by-step Solution
Detailed explanation
\( I_{max} = V \sqrt{\frac{C}{L}} \) \( I_{max} = 10 \, \mathrm{V} \sqrt{\frac{4 \times 10^{-6} \, \mathrm{F}}{10 \times 10^{-3} \, \mathrm{H}}} \)
