Problem

A series LCR circuit shows half-power frequencies at

\omega_1 = 9.8\times10^{3}\,\text{rad s}^{-1}

and

\omega_2 = 1.02\times10^{4}\,\text{rad s}^{-1}

. If the inductance is

L = 50\,\text{mH}

, the capacitance

C

is closest to a)

2.0\,\mu\text{F}

0.20\,\mu\text{F}

0.005\,\mu\text{F}

0.02\,\mu\text{F}
