A series RLC circuit resonates at 1000 kHz. At frequency of 995 kHz, the circuit impedance is
- A. Resistive
- B. Minimum
- C. Inductive
- D. Capacitive
Answer: D. Capacitive
Explanation: In a series RLC circuit, below the resonant frequency (f < f_0), capacitive reactance (1/wC) is greater than inductive reactance (wL). Thus, the overall impedance is capacitive.
