The resistor is one of the fundamental elements in engineering. As compared to other fundamental elements inductor and capacitor, the resistor is used in almost all electronic and electrical circuits. It is also known as a linear, bilateral, and passive element. The resistor is available in a different range of values, starting from milliohms to megaohms. It also dissipates a lot of heat when it carries current. Resistor value depends on the resistivity of … [Read more...]
What is Permanent Magnet Stepper Motor : Working & Advantages
In the industrial domain progression, motors hold a very crucial role and their application is enhancing day-by-day. Not only in the power industries, but in many control applications, motors are playing a critical role. With the enhancement of motor control, the usage and implementation also augment every year. So, the stepper motor is a kind of control motor which operates on positioning control having no feedback loop. Stepper motors were formed at the … [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 Varistor : Working and Its Applications
Usually, in electronic circuits, we encounter currents and voltages of the order of milliamperes and millivolts. Electronic circuits have very high input impedance and are very sensitive. Our usual methods of over current protection or over-voltage protection are not applicable here. We need a device that is quick and sensitive. A varistor is a device that meets our requirement and controls voltage spikes very effectively thus protecting our circuit. The … [Read more...]
What is a Chopper Amplifier : Types & Its Applications
In the scope of the electronics domain, we need to deal either with a larger or smaller amplification range of signals. Let us consider the scenario that we need to amplify a signal in the range of millivolts, and this is the signal where the change in volt in correspondence to change in time is very minimal. These signals cannot be amplified using RC coupled amplifier because these signals could not be bypassed through a coupling capacitor. Even the … [Read more...]
What is a Multistage Amplifier : Design, Types & Its Applications
In many of the practical applications, the output of a single-stage amplifier is not sufficient to provide the required bandwidth or gain. So, the enhance either power or voltage gain, the multistage amplifier is required. These kinds of amplifier circuits hold the ability to offer augmented specifications and enhance the circuit performance and so preferred as fundamental building circuits for the development of complicated amplifier networks. This … [Read more...]
What is an Active Low Pass Filter : Working and Its Applications
For the functioning of many electronic circuits, filters hold the most importance. So, people in the domain of electric and electronics, show interest in the development of filters. In general, a filter is termed as the electric network which modifies either the amplitude of phases of the signal corresponding to the frequency. And then the active filter is the analog circuit which is designed using active components usually amplifier. And these active … [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...]
Difference between Resistance and Resistivity
In the electrical and electronics industries, the concepts of resistance and resistivity are the most important ones. One has to be clear regarding why these topics hold prominence and what are differences and comparison? The foremost difference is that resistance opposes the electron flow, while resistivity defines the material’s resistance having the corresponding dimension. So, here is a detailed view of all these topics. This article discusses an … [Read more...]
Differences between DC Series and Shunt Motors
Before knowing about the differences between DC Series and Shunt Motors, let us start to know what a DC motor is. An electric motor that is powered up by direct current is termed as DC motor. In a detailed view, when a current-carrying conductor is positioned in the area of a certain magnetic field, it gains some torque and tends to have a moment. So, this is the same principle where a DC motor also works on. A DC motor is also named depending on the type … [Read more...]
