Question 374: AC fundamentals

Question

An alternating voltage of frequency '$\omega$' is induced in electric circuit consisting of an inductance '$L$' and capacitance '$C$', connected in parallel. Then across the inductance coil

Accepted Answer

In a parallel $\mathrm{LC}$ circuit at $\omega^2=\frac{1}{\mathrm{LC}}$, the current is minimum.
As current and voltage are out of phase by $90^{\circ}$, the voltage would be maximum.

Answer

current is maximum when $\omega^2=\frac{1}{\mathrm{LC}}$

Answer

current is zero

Answer

voltage is minimum when $\omega^2=\frac{1}{	ext { LC }}$

Answer

voltage is maximum when $\omega^2=\frac{1}{\mathrm{LC}}$
