Answer:

a)

[tex]z=561.7[/tex]

b)

[tex]z=214.1[/tex]

Explanation:

L = inductance of the Inductor = 3.14 mH = 0.00314 H

C = capacitance of the capacitor = 5.08 x 10⁻⁶ F

a)

f = frequency = 55.7 Hz

Impedance is given as

[tex]z=\frac{1}{2\pi fC} - 2\pi fL[/tex]

[tex]z=\frac{1}{2(3.14) (55.7)(5.08\times 10^{-6})} - 2(3.14) (55.7)(0.00314)[/tex]

[tex]z=561.7[/tex]

b)

f = frequency = 11000 Hz

Impedance is given as

[tex]z= - \frac{1}{2\pi fC} + 2\pi fL[/tex]

[tex]z= - \frac{1}{2(3.14) (11000)(5.08\times 10^{-6})} + 2(3.14) (11000)(0.00314)[/tex]

[tex]z=214.1[/tex]
