Reactance and Frequency Relationships

Consider the following statements and choose the correct option.
Statement A: Capacitive reactance is inversely proportional to frequency.
Statement B: Inductive reactance is directly proportional to frequency.
 
Both statements A and B are correct
Both statements A and B are incorrect
Statement A is correct and B is incorrect
Statement A is incorrect and B is correct

Solution:

The formulae are \(X_C = \frac{1}{2\pi f C}\) (inversely proportional) and \(X_L = 2\pi f L\) (directly proportional). Hence, both statements are correct.
