Study Notes
LRC Circuit
Components
- L: Inductor (coil of wire)
- R: Resistor
- C: Capacitor
Characteristics
- A series LRC circuit is a type of resonant circuit
- Exhibits electrical resonance at a specific frequency (natural frequency)
Resonance in LRC Circuits
- Occurs when the inductive reactance (XL) equals the capacitive reactance (XC)
- Frequency at which resonance occurs is called the resonant frequency (fr)
- At resonance, the circuit impedance is purely resistive (Z = R)
Impedance in LRC Circuits
- Total impedance (Z) is the vector sum of resistive, inductive, and capacitive impedances
- Z = √(R^2 + (XL - XC)^2)
Phasor Diagrams
- Used to represent the voltage and current relationships in an LRC circuit
- Voltage and current phasors are represented as rotating vectors
- Phasor diagrams help analyze the circuit's behavior at different frequencies
Applications of LRC Circuits
- Tuning circuits in radios and televisions
- Filter circuits (band-pass, band-stop, high-pass, low-pass)
- Oscillators and resonant circuits in electronic devices
