Question

You need to make a series ac circuit having a resonance angular frequency of 1400 rad/s using a 136 ohm resistor, a 10.3 /muF capacitor, and an inductor. Part A What should be the inductance of the inductor? Part B What is the impedance of this circuit when you use it with an ac voltage source having an angular frequency of 1400 rad/s ?

Explanation / Answer

a) w = 1/sqrt(LC)

L = 1/w^2 *C

L = 49.5mH

b)

as the circuit will be in resonance

so Xc = X(L)

impedence = 136 ohm
