Introduction to Electronics Capacitors, quick introduction

This guide will help you understand electronic circuits—the fundamental building blocks of modern technology. Electronics are all around us, embedded in countless devices we use daily, and it all starts with these circuits.

Capacitors, quick introduction

Capacitors are components that store and release electrical energy in an electronic circuit. They play a few vital roles in various circuits: from smoothing out fluctuations in voltage to time-keeping in watches, and from filtering noise to storing power temporarily. A capacitor is typically composed of two conductive plates separated by an insulating material called a dielectric.

Electrical voltage is applied to charge the capacitor, and once charged, it holds the energy until discharged. The ability of a capacitor to store charge is measured in Farads (F), and capacitors can vary widely in their capacitance values based on their intended use in an electrical circuit.

Capacitor Key Facts:

  • Function: To store and release electrical power
  • Unit of Measurement: Farads (F)
  • Role: Filtering, timing, and energy storage
