Consider an RLC series circuit. The impedance of the circuit increases if X_C increases. A) true only if X_L is greater than or equal to X_C B) true only if X_L is less than or equal to X_C C) always true D) never true

Question

Quizplus · Accepted Answer

The impedance of an RLC series circuit is given by Z = √(R² + (X_L - X_C)²). If X_C increases and X_L ≤ X_C, the term (X_L - X_C)² increases, thus increasing the impedance.
