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
