# Problem: A capacitance C and an inductance L are operated at the same angular frequency. Part AAt what angular frequency will they have the same reactance?Part B If L = 5.50 mH and C = 3.70 mu F, what is the numerical value of the angular frequency in part A?Part CWhat is the reactance of each element?

###### FREE Expert Solution

The reactance of an inductor:

$\overline{){{\mathbf{X}}}_{{\mathbf{L}}}{\mathbf{=}}{\mathbf{\omega }}{\mathbf{L}}}$

The reactance of a capacitor:

$\overline{){{\mathbf{X}}}_{{\mathbf{C}}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{\omega }\mathbf{C}}}$
