An LC circuit oscillates with angular frequency ω equal to:
Aω = 1 / √(L C)
Bω = √(L C) direct
Cω = L · C product
Dω = L / C ratio
Answer & Solution
Correct answer: A. ω = 1 / √(L C)
1. Differential equation: L (d²q/dt²) + q/C = 0.
2. SHM with ω² = 1 / (L C) ⇒ ω = 1 / √(L C).
3. Energy oscillates between the magnetic energy of L and the electric energy of C.
