Question

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?

• A. \( B \)
• B. \( C \)
• C. \( D \)
• D. \( A \)

Answer 1

The Correct Option is C

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 \( C \).
