Most Important Selected Qs for JEE AdvancedPhysicsAlternating Current
At a moment (t=0) , when the charge on capacitor C₁ is zero, the switch is closed. If I ₀ be the current through inductor at t=0 , for t 0 (initially C ₂ is uncharged)
Options
- Amaximum current through inductor equals I ₀ / 2 .
- Bmaximum current through inductor equals C ₁ I ₀ C ₁+ C ₂ .
- Cmaximum charge on C ₁= C ₁ I ₀ L C₂ C ₁+ C ₂ .
- Dmaximum charge on C ₁= C ₁ I ₀ L C ₁+ C ₂ .
Correct answer
D. maximum charge on C ₁= C ₁ I ₀ L C ₁+ C ₂ .
Step-by-step solution
aligned & 1 2 q^2 (C₁+C₂ ) = 1 2 L I₀^2 & q= L (C₁+C₂ ) I₀ & q₁= q C₁+C₂ C₁=C₁ l₀ L (C₁+C₂ ) aligned
