What are the applications of a capacitor?

Explanation

(i) The applicartions of capacitor are capcitors is used in most people are now familiar with the digital camera to emit a flash. The flash which comes from the camera when we take photographs is due to the energy released from the capacitor, called a flash capacitor.
(ii) Capacitor is used in the 20 heart defibrillator that is used to give a sudden surge of a large amount of electrical energy to the patient.s chest to retrieve the normal heart function. This defibrillator uses a capacitor of 175 `muF` chaeged to a high voltage of around 2000 V.
(iii) Capacitors are used in the ignition system of automobile engines to eliminate sparking.
(iv) Capacitors are used to reduce power fluctuations in power supplies and to increase the efficiency of power transmission.
