📚 Understanding Capacitors
What is a Capacitor?
A capacitor is an electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material (dielectric).
Formulas
Charge: Q = C × V
Energy: E = ½ × C × V²
- Q: Charge stored (Coulombs or µC)
- C: Capacitance (Farads or µF)
- V: Voltage across capacitor
- E: Energy stored (Joules or mJ)
Common Applications
- Filtering: Smoothing power supply ripple
- Coupling: Passing AC signals while blocking DC
- Timing: RC circuits for delays and oscillators
- Energy Storage: Flash photography, power backup
- Decoupling: Reducing noise in digital circuits
Capacitor Types
- Ceramic: Small, cheap, good for high frequencies
- Electrolytic: High capacitance, polarized, for power supplies
- Film: Stable, low loss, for audio and precision circuits
- Tantalum: Compact, stable, expensive
