What is an LRC Circuit?
An LRC circuit consists of an inductor (L), resistor (R), and capacitor (C) connected in series or parallel. It is used in filters, oscillators, and tuning circuits.
Key Parameters
- Impedance (Z): Total opposition to current flow.
- Resonant Frequency: Frequency at which impedance is minimized.
- Phase Angle: Difference between voltage and current phases.
FAQs
- What is resonance? When inductive and capacitive reactances cancel each other out.
- How is impedance calculated? Z = √(R² + (XL - XC)²).
