Capacitors in Electrical Engineering

The capacitors have the ability to store the charges, this is a passive electronic component and plays an important role in the electrical components. In an electric field, the capacitors are used to store the energy. Moreover, their use is very much common in various kinds of electric circuits, which are basically used in different electronic devices. Its original name was condenser. The range of these capacitors can vary as per their use, like there can be small capacitors to be used for the resonance circuits, and there can also be large capacitors, but it is important to remember that regardless of their size and use, their basic purpose remains the same, which is to store the charge. The basic capacitor may have two or more than two conductive plates. There are many major and minor applications of the capacitor in the electrical circuits that are given below

Charging the fan of Application of Capacitors

Capacitor is present in every fan this is because these capacitors gives the initial charge to the fan when turn on the power. If these capacitors are not used in the fans, so you need to use hand power for giving a starting push.

Turing on of tube light of Application of Capacitors

The capacitor is also used in the tube lights, when you turn on the light the capacitor is used for the initial charge.  If there is no capacitor present in the tube light so it takes a lot of voltage to turn on the light. When you turn on the light the voltages transfer to the capacitor and then the capacitor gives the initial push to the charges present in the tube light (Kaiser, 2012).

Battery holds up of Application of Capacitors

The type of capacitor used for battery hold up is the super capacitor. These super capacitors are used for holding up the batteries. This is used when the battery is down to the 9% so the super capacitors acts to hold the battery at that time that acts as the standby time for the battery (Kularatna, 2014).

Blockage of DC of Application of Capacitors

The capacitors are also used to block the path for the DC voltage. This system is used where there is no need of the DC current in the circuit so the capacitors are used to block the path for the DC current and allows AC current to flow through the circuit (Deshpande, 2012).

Capacitor used to convert from AC to DC of Application of Capacitors

These capacitors are also used in the conversion of AC to DC voltages. There are two types of capacitors that are used in the circuit that are non polar and polar capacitor. The main aim of these capacitors in the circuit is that they are involve in removing the ripples from the DC voltage wave, because we need a smooth DC voltage in the output of the circuit so these capacitors help to make DC wave more smoother (Williams, 2013).

Voltage doubles of Application of Capacitors

The capacitors are also used for doubling the AC voltages, for using the capacitors as for making the AC voltages double we need to make capacitor arrangement like that so this arrangement will provide double voltages at the output of the circuit. (Kularatna, 2014)

Capacitors as a filter of Application of Capacitors

The most important application of the capacitors is they worked as the filter in the circuit. There are two types of filters the one is low pass filter and the other one is high pass filter and for making the low pass filter the capacitor is attached in parallel with the output of the circuit and for making the high pass filter the capacitor is attached in series with the output of the circuit (Kularatna, 2014).

Capacitors used for discharge unit of Application of Capacitors

 The capacitors are used for as the discharge unit in the circuit means that these capacitors are used to release the charges and this releasing of charge is used as the triggering or may be as for ignition in the car. In the electric car the capacitors are used as the initial charge for starting (Kularatna, 2014).

For making simple amplifiers of Application of Capacitors

The amplifiers are made with the help of simple transistors for smoothing the signal and also for making the output of the amplifier stable these capacitors are used in the parallel with the circuit (Williams, 2013).

The Snubber capacitor of Application of Capacitors

The capacitors are used to limit the high voltage from the inductive loads. These capacitors have the ability to restrict the high voltages from passing through the circuit when inductive loads are used so these capacitors hold the whole charge itself (Kularatna, 2014).

Capacitors as oscillator of Application of Capacitors

The capacitor is also used for making spring like oscillators. The capacitors are used in that circuit like a oscillator. You just need to set the resistance value and attach the capacitor for making oscillatory frequency (Kaiser, 2012).

Capacitors used for power factor correction of Application of Capacitors

The capacitors are also used for correct the power factor in the electrical distribution system. The power factor correction is a very important task in any electrical systems. The power factor value must be near to whole number one. For power factor correction the capacitors are attached as the three phase load in the electric circuit (Deshpande, 2012).

Capacitors as the energy storage of Application of Capacitors

The capacitors are used for storing the charge they have the ability to store the electric charge when it is connected to the charging circuit, means that the capacitor may acts as the temporary battery. In the car the capacitors are used to store the electric charge in the audio system when you need to turn on the amplifier the stored charge used for the initial push (Kularatna, 2014).

The capacitors are also used in many power electronic circuits that are used for converting from AC to DC, DC to AC, DC to DC and also for AC to AC circuits.

Conclusion of Application of Capacitors

It can be concluded that capacitors have a major role in the field of electrical engineering as they are able to perform so many important electrical functions for various kinds of electrical devices. The energy storage ability is not the only function they perform; rather they are very useful to power on the tube lights, and fans. Moreover, when it is needed to block DC voltage or convert AC voltage to DC voltage, they are critical for these functions. They are also beneficial in making amplifiers; discharging units, power factor correction, as well as they is used as oscillators. All of these functions are important functions in the field of electrical engineering.
