An LCR circuit, also known as a resonant circuit, tuned circuit, or an RLC circuit, is an electrical circuit consisting of an inductor (L), capacitor (C) and resistor (R) connected in series or parallel. The LCR circuit analysis can be understood better in terms of phasors. A phasor is a rotating quantity. The quality factor is defined as the ratio of the voltage drop across the inductor or capacitor to that of applied voltage. It measures the sharpness of resonance of an LCR circuit.
When resonance takes place in LCR circuit?
Answer & explanation
Correct answer: option 3
Resonance can take place if inductive and capacitive reactance are equal and opposite.
