MCQ

At what angular frequency $\omega $ the following circuit consumes maximum power?.......$rad/s$

✓
$12.5$
B
$50$
C
$80$
D
$64$

✓

Answer

Correct option: A.

$12.5$

a
a
$\omega=\frac{1}{\sqrt{\mathrm{LC}}}=\frac{1}{\sqrt{160 \times 40 \times 10^{-6}}}=\frac{1}{\sqrt{6400 \times 10^{-6}}}$

$\frac{1}{80 \times 10^{-3}}=\frac{1000}{80}=12.5 \mathrm{\,rad} / \mathrm{s}$
