What is Varistor : Working and Its Applications

July 27, 2020 By Wat Electrical Leave a Comment

Characteristics

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

July 19, 2020 By Wat Electrical Leave a Comment

Chopper Amplifier

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

July 17, 2020 By Wat Electrical Leave a Comment

RC Coupled Amplifier

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

July 15, 2020 By Wat Electrical Leave a Comment

LPF

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

July 13, 2020 By Wat Electrical Leave a Comment

Ceramic Capacitor

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

July 12, 2020 By Wat Electrical Leave a Comment

Differences 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

July 10, 2020 By Wat Electrical Leave a Comment

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...]

What is a Submersible Pump : Types & Its Working

July 8, 2020 By Wat Electrical Leave a Comment

Submersible Pumps

In the ancient period itself, the concept of good pump has discovered and moved on from that period, there were many progressions and changes that happened in the development of the pump’s design, construction, functioning, and others. The one kind of pump which we are going to discuss today is “Submersible Pump”. In the year 1916, Armais Sergeevich Arutunoff initially coined this pump, and the first usage was after the 1950’s only. Initially, these … [Read more...]

What is an Ohmmeter : Working Principle & Its Types

July 6, 2020 By Wat Electrical Leave a Comment

Ohmmeter

Initially, ohmmeters were evolved based on the design construction of a meter known as “Ratiometer”. Ohmmeters under this classification only calculate the value of resistance because they are not simply integrated into the multimeter construction. Insulation testers which depended on a hand moved generator also works on a similar operation. This makes sure that indication was completely autonomous of the developed voltage. Following this, various designs … [Read more...]

What are Digital Sensors : Types and Their Uses

June 30, 2020 By Wat Electrical Leave a Comment

Digital Sensor

Electrochemical and electrical sensors are usually one part of the measuring sequence. And this sequence generally comprises of a sensor, transmitter, and a cable. And the foremost classification of sensors is analog and digital. The digital sensor technology is more substantial in regard to its extensive reliability and exactness. Digital sensors are the contemporary replacements of analog sensors because of few drawbacks in the analog type of sensors. … [Read more...]
