Which of the following graphs represents the correct variation of inductive reactance \[{{X}_{L}}\] with frequency v?

A)          

B)

C)        

D)

Correct Answer: B

Solution :

(b) Inductive reactance,             \[{{X}_{L}}=\omega L=2\pi vL\Rightarrow {{X}_{L}}\propto v\] Hence, inductive reactance increases linearly with frequency.
