Capacitors
Capacitors are devices which are used to store electric
charge and electrical energy. it
consists of two conducting objects separated by some distance. Capacitors are widely used in many electronic
circuits and have applications in many electronic circuits and have
applications in many areas of science and technology.
Applications of capacitors
In many ways capacitors are used in the electronics world, here
some other interesting applications are given.
Most people are now familiar with mobile cameras. Capacitors
are used in this digital camera also. The flash which comes from the camera
when we take photographs is due to the energy released from the capacitor
because capacitors store that energy for this flash. These capacitors are
called flash capacitors.
In the medical
field, we know that heart defibrillators are used to give a sudden surge
of a large amount of electrical energy to the patient’s chest to retrieve normal heart function. These defibrillators use a capacitor to store high
voltage like 2000 V.
In automobiles, engineering is widely used. It is used in the ignition system of the engine to eliminate
sparking. This means to start the engine with the energy of capacitors.
In general
electric power supply problems are corrected with the capacitors. Capacitors are
used to reduce power fluctuations in power supplies and to increase the
efficiency of power transmission.
