Understanding Capacitors

Definition and Functionality

• A capacitor stores electric charge.
• Functions similarly to a battery but stores energy differently.
• Key Differences:
  • Cannot store as much energy as a battery.
  • Can charge and release energy much faster.

Uses in Circuits

• Capacitors are found in almost every circuit board.
• Acts like a water tank in electrical circuits by storing energy.
• Purpose:
  • Releases energy to smooth out interruptions in the power supply.
  • Prevents light from flashing in circuits that are turned on and off rapidly.
  • When connected in a circuit, capacitors allow lights to remain on during brief interruptions by discharging energy.

Structure of a Capacitor

• Components:
  • Two conductive metal plates (commonly made from aluminium).
  • Separated by a dielectric insulating material (e.g., ceramic).
• Dielectric Material:
  • Polarizes in the presence of an electric field.

Conclusion

• Capacitors play a crucial role in maintaining a stable power supply in circuits.
