Overview
This calculator analyzes the properties of proper Series or Parallel RLC circuits, specifically their resonance characteristics.
💡
Pro Tips
Series RLC: High impedance at resonance (Band-stop), Q increases with L/C.
Parallel RLC: Ideal Parallel RLC has infinite impedance at resonance (Band-pass voltage). Note: Real parallel circuits often have resistance in series with the inductor.
Bandwidth is the range of frequencies where the power is at least half the max power.

Fun Facts
"Q factor describes how under-damped an oscillator is."
"Higher Q means a narrower bandwidth and sharper resonance."
