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 $$\omega^2=\frac{1}{	ext { LC }}$$
