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...]
What are Capacitors in Series : Connection, Formula & Its Examples
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...]
What is Electrolytic Capacitor : Working & Its Applications
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...]
What is a Displacement Current : Formula & Its Significance
In the field of electromagnetism, let us assume that the electric displacement field is given by D. The electric field can be observed across a conductor, or in a vacuum space. Vacuum in the sense if they assume that we have connected a capacitor, then the gap between the plates is assumed as a vacuum. After some time, once the capacitor is charged, even if we remove the source, there exists some amount of electric field across the plates of the capacitor. … [Read more...]
What is a Capacitor : Construction & Its Working
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...]
What is Ceramic Capacitor : Construction & Its Working
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...]
What is a Capacitor Bank : Working and Its Calculation
When a number of capacitors are connected together it forms a capacitor bank. They can be connected in series or parallel. A capacitor bank has numerous advantages and applications. Most of the time, these are used for reactive power compensation and power factor improvement. The arrangement of these can be done at substation or power plants. The unit for capacitance in Farads. A capacitor bank of lower scale is frequently used in industrial buildings, … [Read more...]
What is Polyester Capacitor : Number Coding & Colour Coding
As a widely used electrical component capacitor plays an active role in the functioning of any circuit and without it the circuit design will not be completed. It is an important and useful component because it has features like energy storing capability, minimizing sudden voltage changes, selectivity of frequencies, bypassing of frequencies, phase shifting, etc. The Capacitor consists of two electrode plates which are separated by an insulating or … [Read more...]
