Difference Between Capacitor and Battery

Hello, readers welcome to new post. Here we will discuss Difference Between Capacitor and Battery. A battery is a device that transforms chemical energy in electrical energy and provides static charges to deliver the power. The capacitor is an electronic component that is used for energy storage in the form of an electrical field.

Both of these are used for energy storage and proving the energy but come with differences that we will discuss here. So let’s get started Difference Between Capacitor and Battery.

What is Capacitor

The capacitor is a passive component that comes with two pins and stores energy in the form of an electrical field.

The capacitor effect is called capacitance. Some value of capacitance exists in the conductors in circuitry but the addition of capacitors enhances the capacitance.
Capacitors are also called condensers and condensators.
There are different types of capacitors based on shapes and structures.
Most capacitors consist of two pins that are metallic plates and have dielectric material for separation.
The capacitor can be foil thin sheet and electrolyte. The use of nonconducting dielectric material works to enhance the charging capacity of the capacitor.
The material used for dielectrics is glass, ceramic paper, mica, and air.
Capacitors are used in different devices as electrical circuits.
If volts are given to the capacitor terminals through a battery electrical field is created about the dielectric that results in positive charges on one electrode and negative charges on the other electrode.
There are no current flows in the dielectric material. But the flow of charges through the source circuit.
The energy stored in the capacitor is 1/2 CV2.
It is an insulator for DC means dc can not pass through it
Current leads volts by 90 degrees in the case of AC circuits
For DC circuits capacitor connects in series combination with resistance current at the start large and then goes to 0
The unit of the capacitor is Farad
Commonly used types of capacitors are Electrolyte, and ceramic.
It works as a short circuit for AC circuits meaning AC passes through it and blocks DC
The capacitor gets energy from the circuitry stores it and then releases that energy.
It is a passive element
Its charging and discharging speed is larger than the battery normally one to ten seconds
Its life cycle is 30000 hours
volts can store 2.3 to 2.75 V
Expensive than the battery
Operating life is ten to fifteen year

What is Battery

A battery is an electric power source that comprises of one and more than one electrochemical cell having external points for delivering the power.
During delivery, the power-positive terminal works as a cathode, and the negative terminal is the anode.
The negative pins of battery electrons’ sources move through the exterior circuitry to a positive point.
If the battery is attached to load reduction and oxidation reaction transforms the high energy reactants to less energy output.
The primary type of battery is only used one time the alkaline battery is a primary battery.
The secondary battery can be recharged again and again. Its examples are lead-acid batteries of automobiles and lithium-ion batteries.
The battery used to give power to the circuit
It is the active component
It works as a dc device since provides static charges
During the discharging gives the constant value of volts
Its charge and discharge time is high normally ten to sixty minutes
Its specific power is 1000 to 3000
It can work for five to ten years
Its structure is smaller than the capacitors

Capacitor vs Battery

Battery stores potential energy in the form of chemical reactions and capacitors store potential energy in the form of electrical fields. Capacitor voltages are variables.
A battery stores the larger electric charges and capacitors used for high voltage circuits and high frequency uses.
The rate with which a capacitor can charge and discharge is faster than a battery called the charge/discharge rate.
Both are used for storing electrical energy battery stores in the form of chemical energy and capacitors in the form of a field.
For battery charging polarity of the circuit is reversed and saved for capacitors used in the circuit.
