For analog & digital devices, system noise has become a major problem so they have become very sensitive to disturbances from signal lines & power. So the capacitors like decoupling and bypass within a circuit are used very close to the IC power pins to provide high transient current to an integrated circuit & decrease power ripples. Analog circuits like audio amplifiers produce a cracking noise or hum throughout their operation whereas digital … [Read more...]

As we know that in the domain of electronics, capacitors are the most prominent devices which are extensively used in the design of various circuits. The key advantage of using a capacitor in electronic circuits is, its ability to store the electrical energy between its plates. These are the most considered components used for controlling the charge flow in the circuit. Capacitors along with devices like inductors and resistors come under the … [Read more...]

It was known that in the year 1745, Kleist discovered that charge can be accumulated by accomplishing the connection between electrostatic generator through a wire to water in a glass jar. The component that is used to store the charge is called a capacitor. These capacitors are categorized as non-electrolytic and electrolytic depending on their polarities and dielectrics. The necessary amount of capacitance is obtained when these capacitors are connected … [Read more...]

The theory in the electrochemical procedure, metals such as aluminum, niobium, cadmium, and others create an oxide coating that obstructs the actual flow of current directions but allows to flow in the opposite paths. This phenomenon was initially observed by Johann Buff in the year 1875 and its implementation was done by Ducretet. The manufacturer of accumulators namely "Charles" came to know that the oxide coating stays stable in the case of alkaline and … [Read more...]

The word capacitance is derived from capacity, capacity is to contain, or store. a capacitor refers to a device that is capable of storing electrical energy. Unlike the storage of water which can be stored in ponds, lakes, tanks and our seas which are our almost unlimited reservoir of water we have very limited options for direct storage of electrical energy. As a matter of fact, we have only one option as a battery to store electrical energy in the form … [Read more...]

The word capacitor comes from ‘capacity’ and a capacitor has the capacity to store electrical power. Capacitors are an integral part of electrical circuitry, in power circuits, their role as power factor improver and power storage device cannot be underemphasized. After batteries, the capacitor is the only device that can store electrical power. Capacitors are also used as power quality improver. However, in electronic circuitry, capacitors have many more … [Read more...]
