Reactance and Frequency Relationships – Rankers Physics

LR, RC and LCR Circuits: Practice Problem & Solution

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

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of LR, RC and LCR Circuits. Understanding the underlying formula is key to arriving at the correct answer below:

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.
