The figure shows variation of \( R \), \( X_L \), and \( X_C \) with frequency \( f \) in a series LCR circuit. Then for what frequency point is the circuit capacitive?
- \( B \)
- \( C \)
- \( D \)
- \( A \)
The Correct Option is C
Solution and Explanation
In a series LCR circuit, the circuit behaves capacitively when the capacitive reactance \( X_C \) is greater than the inductive reactance \( X_L \). This occurs when the frequency reaches the point where \( X_C \) exceeds \( X_L \), which is shown at point \( C \) in the graph. Thus, the circuit becomes capacitive at frequency point \( C \).
