Question: Define the reactance X of an L-R-C circuit to be X = XL Xc. (a) Show that X = 0 when the angular frequency

Define the reactance X of an L-R-C circuit to be X = XL – Xc.
(a) Show that X = 0 when the angular frequency w of the current is equal to the resonance angular frequency w0.
(b) What is the sign of X when w > w0?
(c) What is the sign of X when w < wo?
(d) Graph X versus w.
