Question

An $L-C-R$ series circuit has a maximum current of $5A$. If $L=0.5H$ and $C=8\mu F$, then the angular frequency of $AC$ voltage is :

• A. $500$rad/s
• B. $5000$ rad/s
• C. $400$ rad/s
• D. $250$rad/s

Answer 1

Answer: (A)

$500$rad/s

$\omega =\frac{1}{\sqrt{LC}}=\frac{1}{\sqrt{0.5\times 8\times {10}^{-6}}}$
$=500$rad/s
