Question

Write the application of capacitors.

Answer 1

Hint:Capacitors are the devices which are used to store energy, that is, they have the capacity to store energy in the form of charge. Because of this property of storing energy, it can be used in many places, though the capacitors used should be in a bulk amount as less number of capacitors don’t store much larger amounts of energy.

Complete answer:
Capacitors are devices which store electrical charge. They are a basic component of electronics and have a number of varied applications. The basic and the most common use for capacitors is energy storage. Some other uses of capacitors include power conditioning, signal coupling or decoupling, electronic noise filtering as well as in remote sensing. Because of its varied applications, capacitors are utilized in a good range of factories and became an important part of lifestyle.
• Capacitors have been used to store energy in electrical form since the 18th century. A single capacitor or a few of them generally don't hold an excellent deal of energy, providing merely enough power for electronic devices to use during temporary power outages or once they need additional power.
• Capacitors are used as sensors to measure a variety of things, including humidity, levels of fuel as well as mechanical strain. The capacitance of a tool mainly depends on its structure. Changes in the structure can be measured as a loss or gain of capacitance.
• When they are charged, capacitors would allow the AC signals to pass while blocking the DC signals. They can effectively split these two signal types, cleaning the availability of power. This effect has been exploited to separate or decouple different parts of electrical circuits to scale back noise which could lead on to reduction of efficiency.
• Dynamic Random Access Memory known as DRAM devices use capacitors to store binary information as bits. The device reads a single value when the capacitor is charged and another when discharged.

Note:When capacitors are connected in parallel, the voltage across the battery remains constant and their total capacitance is greater than that of the largest capacitor. While when capacitors are connected in series, the charge across the battery is constant and the total capacitance is lower than the lowest capacitor.
