THE PRACTICE STUDIO
Go slowly. Ask why. Make it yours.
PRACTICE / LC oscillations
The capacitor starts with only part of the energy
Immediately after switching, an isolated ideal LC loop has L = 0.50 H, C = 8.0 μF, capacitor voltage +3.0 V and current +0.016 A in the direction charging its positive plate.
What is the greatest capacitor voltage magnitude reached subsequently?
Organize the givens & assumptions
- L = 0.50 H
- C = 8.0 μF
- Initial capacitor voltage: 3.0 V
- Initial charging current: 0.016 A
Lossless fixed L and C, lumped circuit, no source after switching. Initial current and capacitor voltage are both part of the specified starting state.
- A
- B
- C
- D
