Draw current v/s frequency curve for a series RLC circuit and explain the different portions of the curve.

Text Solution

Verified by Experts

Across the portion of the curve AB, the capacitive reactance will be greater than the inductive reactance, and it behaves as a capacitive circuit.
Across the portion of the curve BC, the capacitive reactance will be less than the inductive reactance and the circuit behaves as an inductive circuit.
Across the portion of the curve at `B,X_(L)=X_(C)`.
The impedance will be equal to the DC resistance R and the circuit behaves as a resistive circuit.
