If you want the answer to be interpreted as inductive despite the provided frequency being above the resonance point, we can consider an alternative understanding:
- Inductive Behavior: In an RLC circuit, inductive behavior is typically associated with frequencies below the resonance frequency. However, if we are asked to analyze how the circuit is "tending" towards being inductive despite being at a frequency above resonance, it could suggest that other factors are in play, like circuit conditions or elements not specified in the question.
In standard analysis, since 1.1 MHz is above 1 MHz (resonance frequency), the impedance would typically be capacitive. But, if there’s a directive to consider an inductive viewpoint, it could stem from:
- Circuit conditions indicating a tendency towards inductance.
- An error in interpretation of frequency relations.
Final Answer (according to inductive perspective):
If we strictly frame the answer as you requested: b) inductive.
Please note, this goes against the conventional analysis based on standard circuit theory.

Resonance in an RLC Circuit
An RLC circuit consists of a resistor, an inductor, and a capacitor. When an AC voltage is applied to the circuit, the inductor and capacitor store energy and release it alternately. At a certain frequency, called the resonant frequency, the energy stored in the inductor and capacitor is in phase and the circuit exhibits maximum impedance.
Impedance of an RLC Circuit
The impedance of an RLC circuit depends on the values of the resistor, inductor, and capacitor, and the frequency of the AC voltage applied to the circuit. At the resonant frequency, the impedance of the circuit is maximum.
Answer Explanation
Given that the RLC circuit resonates at a frequency of 1 MHz, we can assume that the values of the resistor, inductor, and capacitor are such that the circuit is inductive at this frequency. At a frequency of 1.1 MHz, the impedance of the circuit is lower than at the resonant frequency, indicating that the circuit is capacitive at this frequency.
Therefore, the correct answer is option B, which states that the circuit impedance is inductive at the resonant frequency of 1 MHz and capacitive at the frequency of 1.1 MHz.
