Question : 152 of 200

Marks: +1, -0

A circuit with a resistor, inductor and capacitor in series is resonant of fo Hz. If all the component values are now doubled the new resonant frequency is :

$f_o/4$
$2f_ o$
$f_ o$
$f_ o/2$

Validate

Solution:

∵

\f_ 0 = 1 / {2 π√{LC}

Now resonant frequency

\f _{\new} = 1 / {2π√{ 2L× 2C}}=\f_0/ 2
