In RLC series circuit when the frequency of AC source is very low, the circuit an:
Correct answer: B. capacitive circuit
- A. resistive circuit
- B. capacitive circuit
- C. inductive circuit
- D. resonant circuit
Explanation
At low frequencies, the series circuit is capacitive as Xc>Xl, but at higher frequencies, the series circuit is inductive as Xl>Xc. With the decrease in frequency, it becomes more capacitive, i.e., the current decreases, and it changes from inductive to capacitive.

About AC Through Resistor, Capacitor and Inductor
Alternating current through a resistor, capacitor and inductor involves phase relationships between voltage and current, reactance, impedance and energy transfer. A resistor keeps voltage and current in phase, while a capacitor and inductor produce opposite phase shifts, a distinction used in circuit diagrams and numerical calculations.
