Tips

  • Capacitance measures a capacitor's ability to store electrical charge
  • Parallel plate capacitors have capacitance C = ε₀εᵣA/d
  • Higher dielectric constant materials increase capacitance
  • Capacitors store energy as ½CV²

Important Notes

  • Charge Q = CV relationship is fundamental to capacitor operation
  • Different capacitor types have different capacitance formulas
  • Units: Farads (F), but practical values are often μF, nF, or pF
  • Dielectric materials affect both capacitance and maximum voltage
