Part A

In a series $\frac{?}{{?}_{R}C}$ circuit, the frequency at which the circuit is at resonance is $f_0.$ If you double the resistance, the inductance, the capacitance, and the voltage amplitude of the ac source, what is the new resonance frequenc

$\frac{f_0}{4}$

$\frac{f_0}{2}$

$f_0$

$4f_0$

$2f_0$
