Capacitors are very good for storing small quantities of electrical energy, for creating timing circuits based on the time it takes a capacitor to charge, and there are also excellent uses of their characteristic of conducting a varying voltage.

∙ 13y agoCapacitors and batteries share a characteristic in that they can both store energy. A battery can store a lot of energy in a small space compared to a capacitor but a capacitor can be charged to it's maximum voltage much faster, in fact, a capacitor can change from discharged to fully charged in fractions of a second. Compare that to most batteries that have a charge cycle time measured in minutes or hours.
A capacitor doesn't hold a charge in the same way that a battery does. Most capacitors will discharge themselves in a period of minutes to days compared to a battery that will retain a charge for months or years.
So, to power a device that uses minimal current for short periods of time with an almost instant recharge period, a capacitor is well worth considering.
Note: Apologies to the theoretical scientists for the not entirely accurate comparisons of the charges.

Whether film capacitors can be replaced with ceramic or mica capacitor?
Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. However, mica capacitors can be replaced with ceramic capacitors in general.
Why do capacitors leak?
Mostly the leakage of capacitors is due to the resistor.
How many capacitors are use in a circuit?
Capacitors store charge. There are many applications for their use. There is no set amount of capacitors in a circuit since it is application dependent.
Active component in resistors and capacitors?
Resistors, capacitors, inductors, diodes are all passive components.
Why are capacitors required to be in capacitor banks?
Capacitor banks are used to control the power factor in a power system. By connecting suitable capacitors the power factor can be controlled / maintained at a desired level. The requirement of a capacitor changes as the load changes dynamically. The same amount of capacitors can not maintain the desired power factor all the time. To be able to connect only the required number of capacitors, multiple (bank of capacitors) capacitors are included in a system. An automatic controller senses the actual power factor and connects and disconnects the capacitors from the bank as required

Are capacitors polarity sensitive?
The capacitors those are polarity sensitive are called electrolytic and tantalum capacitors. These capacitors are labeled as positive and negative.
How are capacitors rated?
Capacitors are rated in Microfarads
What is the difference between electrolytic capacitors and normal capacitors?
because normal capacitors does not have any polaririties.
Whether film capacitors can be replaced with ceramic or mica capacitor?
Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. However, mica capacitors can be replaced with ceramic capacitors in general.
