In RLC series AC circuit if the applied frequency is less than the resonance frequency then which is true?
Correct answer: D. All of the above
- A. The circuit behaves as a capacitive circuit
- B. Xc > XL
- C. Current leads the voltage
- D. All of the above
Explanation
In an RLC series circuit, when the applied frequency is less than the resonance frequency, the capacitive reactance is greater than the inductive reactance (Xc > XL), causing the circuit to behave as a capacitive circuit. In such scenarios, the current leads the voltage. Thus, all the options provided are correct, which makes Option D the correct choice. Each of the other options individually describes an aspect of the circuit's behavior under these conditions.

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.
