In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone.It is a passive electronic component with two terminals.
A capacitor is a two terminals electronic component which stores the electric charge in the electrostatic field and discharge it back to the circuit as electrical energy. An ordinary battery consists of three essential components: a positive terminal (cathode), a negative terminal (anode), and an electrolyte.
Capacitors are good for applications that need a lot of energy in short bursts. The energy storage capacity of a battery or capacitor is measured in watt-hours. This is the number of watt hours a battery or capacitor can store. Usually, batteries have a higher watt-hour rating than capacitors.
A capacitor can store electric energy when it is connected to its charging circuit and when it is disconnected from its charging circuit, it can dissipate that stored energy, so it can be used as a temporary battery. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed.
Batteries are also capable of delivering a consistent power output over a longer period of time. Overall, the choice between using a battery or a capacitor in the automotive industry depends on the specific application and the desired performance characteristics.
One key application of capacitors is in electronic circuits, where they are used to store and release electrical energy. Capacitors can be used to filter out unwanted noise and stabilize voltage levels in electronic devices. They are also commonly used in timing circuits, oscillators, and frequency filters.
These are the basic applications of capacitors in daily life. Thus, the fundamental role of the capacitor is to store electricity. As well as, the capacitor is used in tuning circuits, power conditioning systems, charge-coupled circuits, coupling, and decoupling circuits, electronic noise filtering circuits, electronic gadgets, weapons, etc.

Capacitors have applications ranging from filtering static from radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another but not touching, such as those in Figure (PageIndex{1}). Most of the time, a dielectric is used between the two plates. When battery terminals are connected to an …
The key distinction between a battery and a capacitor lies in how they store electrical energy.
