Depends upon the magnitude of R
View all questions of this test
At resonance in series RLC circuits, both inductive and capacitive reactance cancel each other. So it depends only on resistance.
Hence, the correct option is (A)

Explanation:
An R-L-C circuit is a circuit that consists of a resistor (R), an inductor (L), and a capacitor (C) connected in series or parallel. At resonance, the current in the circuit is maximum and the impedance is minimum.
Magnitude of current at resonance:
The magnitude of current at resonance in an R-L-C circuit depends upon the magnitude of resistance (R). When the frequency of the AC source matches the natural frequency of the circuit, resonance occurs, and the impedance is purely resistive. At this point, the impedance is minimum, and the current in the circuit is maximum. The magnitude of the current at resonance can be calculated using the following formula:
I = V/R
Where I is the current in the circuit, V is the voltage across the circuit, and R is the resistance of the circuit.
Therefore, the magnitude of current at resonance in an R-L-C circuit depends upon the magnitude of resistance (R).
Conclusion:
Hence, option 'A' is the correct answer.
