#### Question

Which of the following plots may represent the reactance of a series LC combination?

Sum

Short Note

#### Solution

(d)

The reactance of a series LC circuit is given by,

`X = X_L - X_c = omegaL - 1/"omegaC"`

⇒ `X =2pi fL - 1/(2pifC) `

The correct relation between the reactance and *f* is represented by the graph in option (d).

`X = 0, "when" X_L = X_c`

Thus plot d represent the reactance of a series LC combination.

Is there an error in this question or solution?
