What you'll learn

  1. Find the peak: Resonance: XL = XC
  2. Most power from the mains: Tune with C at a fixed frequency
  3. Double the resistor: The peak current is V/R
  4. Swap the parts: ω₀ goes as 1/√(LC)
  5. The capacitor side: Which side leads?
  6. More than the supply: The coil's voltage at resonance
  7. Set the sharpness: Bandwidth = R/L
  8. The dark lamp: A side-by-side pair at resonance
