Electrical Resonance series circuit

Question

In an A.C. circuit, containing an inductance and a capacitor in series, the current is found to be maximum when the value of the inductance is 0.5 henry and capacitance is 8 $μF$ . The angular frequency of the input A.C. voltage must be equal to

Moderate

A

500 rad/sec
B

4000 rad/sec
C

5 x 10⁵ rad/sec
D

5000 rad/sec

Solution

For maximum current X_L = X_C
$∴ ωL = \frac{1}{ωC} or ω = \frac{1}{\sqrt{LC}} ω = \frac{1}{\sqrt{\{0 \cdot 5 \times (8 \times 10^{- 6})\}}} = 500$
