In an RLC series AC circuit, if the applied frequency is less than the resonance frequency, then the circuit will be.
Correct answer: B. Capacitive
- A. Inductive
- B. Capacitive
- C. Resistive
- D. None
Explanation
At frequencies below resonance, the capacitive reactance (Xc = 1/2πfC) is larger than the inductive reactance (XL = 2πfL). The larger reactance dominates the circuit's behavior, making it act as a capacitive circuit.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
