Battery vs. capacitor

Battery vs. capacitor

  • While a battery uses chemical reactions to store electrical energy and releases power very slowly through an electronic circuit, capacitors are capable of releasing energy very rapidly.
    • Energy is stored inside the battery in the form of chemical energy which gets converted into electrical energy, releasing electricity through a chemical reaction which eventually generates an electric current.
      • This is why batteries store a lot of charge but they charge/discharge very slowly
  • A capacitor contains at least two electrical conductors separated by an insulator (dielectric). 
    • When an electric field develops across the insulator, it stops the flow and an electric charge is starting to build up on the plates.
