A capacitor is a device used in most electronic devices to store electric charge in order to keep the system functioning. If for example a television was in used for a few hours and then shot down, if aTechnical has to perform some hardware services on the device due to some malfunctions, He needs to handle the capacitor with care or have it discharged before touching it with his bare hands, otherwise he stands the risk of electric shock and consequently death.

Jordancapacitors are the devices that we use to store electric potential energy.not exactly charge.so once a capacitor is charged it retains the charge for a longer time as the potential difference between plates is absent.so no charges flow.But once we touch it we may get a shock as the charges will tend to flow from the capacitor to the earth through our body.thus giving us a shock.that is the only risk involved in the capacitors.

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
