For a pure inductive circuit, the inductive reactance is given by:
\(X_L=2\pi f L\)
where, XL = Inductive reactance
f = Frequency
L = Inductance
Explanation
From the above expression, the inductive reactance is proportional to the frequency.
XL α f
So, if the frequency of the AC source is doubled, then the inductive reactance will also be doubled.
Additional Information For a pure capacitive circuit, the capacitive reactance is given by:
\(X_C={1\over 2\pi f C}\)
\(X_c\space \alpha \space {1\over f}\)
The capacitive reactance is inversely proportional to the frequency.
